My chickens are just a barnyard mix and were hatched August first. I have 15 and can't tell by looking at them what gender they are. Last night two puffed up their necks and fought each other for about five minutes! What should I do? Cull and kill right away? I want to keep one nice rooster. Now that they're all calm I can't tell who it was that was fighting last night. They're still pretty small to eat. I'm trying to build a self-sustaining dual purpose flock.
Thank you for any input and help you have for me
