Don't buy the duck you can buy a bunch of eggs in camp then merge & close the app SO FAST it can only save your dragon book but not changes to your camp. So 3 eggs can get you 5 level 4s, repeat tier 2 nests
More eggs are less likely to save the merging, I've had 8-10 eggs "merge away" never a large quantity. Also works with bubbled dragons, particularly reward rush. Android, I have about a 1,000 bubbles in camp if that makes a difference. Use cloud save if you want as a backup in case you "lose" your eggs/bubble
WOW
