I got 7 Coturnix chicks from a farm when they were about 3 weeks old. They’re now about 8 weeks old and we’ve ended up with 4 hens and 3 roosters. I’m trying to decide which one to keep and I don’t want to make the wrong choice. One is definitely chases the others around a lot more and two of them are much more vocal than the third. Is there a way to tell which would be the best to keep around? I do want to eventually hatch out my own eggs.
