The GENETICS of COLOURS and PATTERNS in chicken feathers
The colours of chicken feathers are caused by just two pigments - eumelanin and pheomelanin. The expression of these pigments in the feathers is affected by genes.
And the patterns of colour are caused by genes, for example by diluting the colour or by restricting it to parts of the bird or parts of the feather itself. The Columbian (Co) gene acts on the bird as a whole, to make a pattern where the black eumelanin is expressed only only the hackle and tail. The Barring gene (B) turns the pigment on and off as the feather grows, causing black and white stripes on each feather.

I am back watching your genetics series
Incredibly easy to understand.... definitely you are born to teach! have watched 6 so far and onto the next... Thank you!! I need to go back and hit "thumbs up" as I have forgotten until this one...
Thank you. I'm glad you like them.
genetics for chickens black and red works for horses too I studied quite a bit on that, you have the main genes, modifiers like dilution or patterns, just like chickens. awwww your chickens aer so pretty.
You do amazing work!
Thank you. I find genetics fascinating.
Fascinating & well done. You are a natural teacher!
I love the variety of breeds in my flock of hens. I willingly sacrifice some egg production with the less productive breeds for their color.
I love having a variety of chickens too - they look pretty in the garden and I love getting a mixture of eggs in the box.
Thank you for the upload!
You are very welcome. I hope you enjoy it and find it useful.
Cant wait for the lacing video! Thanks for the useful information
Lacing is my favourite. I started this whole series because I want to cover lacing.
Amazing
It's fascinating, isn't it.
All your videos are very informative and very easy to understand. Thanks for the uploads
Thank you.
Very very thanks..superb videos
Thank you.
Very interesting
I think it's an interesting topic too.
Your videos are fantastic! Very easy to understand, and hitting all the necessary points to get the basics of chicken genetics.
I bred reptiles for years and often dealt with Het vs Homo, Dom, CoDom, IncDom, and Recessive traits. I wasn't sure how some of the genetics came together for certain chicken colors, comb shapes, patterns etc. and you've really pointed me in the right direction!
Your videos are totally under viewed and are hidden gems!
Thanks again for your hard work :)
Thank you. I made them because I find it such a fascinating subject. That other people enjoy them and find them useful is a real bonus 🙂
@@chickensinmygarden you're knocking them out of the park! Keep it up! I'm subbed and will keep on watching :)
Thank you so much for super video information.. Kindly requesting to do a video to develop a Strain.
Ok this helps so much a little light went off ;)
I have been breeding rabbits for years and started understand the color patterns i got with them
But we got hens this year and wondering how they got their patterns too
This fascinating to me i will be looking at your other genitic videos thanks:)
Excellent! It's a fascinating subject 🙂 my videos are just a tiny peek into the complexity. Maybe they will inspire you to learn more and try some experiments for yourself
@@chickensinmygarden yes we want to hatch Easter egg chicks to go with our isbar and leg bar hens they are about 20 weeks and we will be hatching out eggs soon
Can't wait to watch them all grow
Ok I heard my quail and chickens have a blue and lavender gene in common but I think quail have another one too
I wanted a gray and red bird so I would need to work not with my lavender gene unless I want both colours diluted
Maybe they were talking about 3 diluter genes I can't remember now
I have a Canadian collection of Quail who have had multiple diluter genes used
But if I want to pick a bird out from here to breed with my red hens I would look for one with red at least on his cheeks showing he's not a lavender too
Anyone else come for the poultry information but end up using the video as a asmr like relaxation video, lol.
As long as you are enjoying watching I'm happy. I certainly enjoy making them and I'm delighted that people want to watch them.
I have a question 🙋🏽♂️ about breeding mottling.
if one of the rooster has 2 copies of the mottled gene
Can I breed it to
silver laced, or partridge
Gold laced,or partridge
And use there First generation offsprings to breed back to another rooster with two copies of the mottling gene
Will I get some success in the mottling to show up on the second generation after that?
Yes I think you should.
The original rooster is homozygous for the mottled gene and so looks mottled.
The first generation all have one copy and since it's recessive they won't express that gene, they won't look mottled.
If you mate those back to a homozygous mottled bird (either sex mating will do) half of the offspring will end up with two copies of the mottled gene and so will express that in their feather pattern.
But what I don't know is what would be the effect of the other pattern genes (Co, Ml and Pg) on the expression of the mo gene. Although we know the bird has two mottled genes and will express it somehow I don't know what the feather pattern will actually look like.
If I wanted mottles and only had one rooster to start with, I would choose a plain coloured bird, like a buff Orpington, for the first cross.
On the other hand if you have a mottled rooster and some laced hens and are just wondering what they might produce, then just do it and see. They might look amazing!
You could try it out on the Kippenjungle chicken calculator

Nice video! But i have a question.
So i have 2 chickens. 1 rooster and 1 hen. The rooster has gray feathers with a barred pattern, and the hen has brown feathers, with a laced pattern that is a slightly lighter brown. What colors and patterns could i get if i breed them?
Almost anything - barred, laced, double-laced, columbian, plain, or duckwing patterns,in grey, brown, black, white, and/ or blue. They should be a pretty mixture of chickens 🙂
@@chickensinmygarden Wow! Those are a lot of combinations!
There might be a few less if you know the exact genetic makeup of your two parent birds - for example you said neither of them have white feathers but their chicks could look white if they are carrying the recessive white gene.
@@chickensinmygarden oh! that’s really interesting! Thanks.
Should I be watching the playlist from start to finish instead of happening upon this video first when searching for breeding Orpington chickens for color?
Yes it's probably a good idea unless you are already familiar with avian genetics 🙂
Hi I’m a little confused about the lavender gene. It is a recessive gene why it still can work on both of eumelanin and pheomelanin?
What a gene does (in this case cause dilution of pigments) is not related to whether it is dominant (acts when present in even one dose) or recessive (only shows in the phenotype when present in two doses).
@@chickensinmygarden 😆okay thanks!
can I cross silver polish with white or black polish?
Of course you can. But what colour offspring you get will depend on the genetic background that's causing the black and white.
The silver should behave exactly as I describe in the videos.
The white might be dominant or recessive (I'm not sure for Polish and it might even vary depending on the strain) but it won't be sex linked.
I have a question...
Is the blue plumage a silver base or a gold base?
To my understanding it's not really either. The blue gene only works as a diluter of eumelanin - the black pigment.
Silver works over the gold colour produced by pheomelanin.
Whether a feather would have black colour (maybe diluted to blue) or gold (maybe covered by Silver) depends on the pattern genes. But blue doesn't relate to the gold/silver dichotomy.
I have a video about how the blue gene affects black

Please can you make a video about development of motteled colours in country chikens. As a request 😊😊
As far as I know there is only the one Mottle gene. I'm not sure what you mean by 'country chickens'.
Thanks for your kind attention ☺. Country chicken or Nattu Kozhi is the term used to refer to the many indigenous breeds and/or mixed breed and mongorel chickens which have been raised in the villages of India for centuries. Actually I trying to develop a motteled country chiken. Comparing to other chiken breedes country chikens have very nice body shape and shiny feathers. Most of the chiken are single colours like black, brown, yellow, blue, red, so if you have time please make a video about colour mixing and motteled developments in chikens☺☺please take as request.
Ah I see. Well in order to get mottled chickens you have to have the mottle gene. Are there any chickens in your country that look mottled? Even if they are not the colours you want, as long as they have the pattern you can work with that.
The mottle gene is recessive so if you start with a mottled bird, all the offspring will carry that gene even if they don't look mottled. Then if you cross the offspring to each other or back to the parent bird you will get some birds that look mottled.
I have 2 birds with motteled colour I will try with that. Thanks maam to replying my messeges
I’m so sad how people ruin animals like cows pigs and chickens to make them so fat they can’t even move just to murder them :( but chickens really are gorgeous I love beautiful birds :)
I understand that we wanted juicy meats but sometimes I wonder whether we have gone a bit too far in treating animals like factory products.
Chickens in my garden humans definitely have gone way to far what is your opinion on the being vegan where we don’t treat animals like objects and slaves I would highly suggest it myself all you would have to do is cut the meat and dairy out and just eat your own eggs
