Hellooo! Thanks for taking time to look at this. I need help on building a quail coop for 41 quails. Ideas would be great. Pictures would too. Enough room for all of them. And since Males get aggressive over females, I have to build two, but I dont know how many males or females I have I would just say 20.5 Sq. ft per cage. How old do they have to be for me to be able to find which gender? Thanks! Remember to give me alot of details because I'm new at this!
