Hi again! As my babies are just over two months, and have very different quacks/sounds, i believe i know 3 are drakes for sure, (their tails are starting to show a curl too) and possibly one or two more, out of my 8 are drakes!!! :-O what kinds of problems will this cause? They all get along great now, stick close together and watch out for each other. they are in a coop/shed all night, and a small run during most of the day, then free range when i get home from work. will i need to seperate them? thanks!
