Chicken lady attacked by angry mama duck

Our mama duck had a clutch of eggs that she sat on. Two of the entire clutch were good, the rest were bad. Mama duck took the first hatched duckling and ran off leaving the second egg abandoned so we threw it in our incubator with some other eggs. Several other duck eggs hatched and we kept giving ducklings to mama duck. She's very possessive and my attempt at a cute duckling video morphed into a duck attack.
