So i have 7 babies (almost a month old). Supposedly BUFF BRAHMAS, but i highly doubt it based on pictures I've seen. Up till now they have been pretty mellow, except one which we suspect MIGHT be a rooster. In the last few days they have stepped up the sparring. This morning when i had them out of the Dog Crate (it's a large one with plenty of roosts) they really started going at it. It was the first time i'd seen them actually make contact and pull at each other instead of small nips. It wasn't the possibly rooster making the fuss either. Scary. Is this normal? We love them so much. The crate is for a large dog...I can't imagine what could be bigger unless we built something. Unfortunately we are trying desperately to get the coop and run finished so its taking up all our time... Any words of wisdom or comfort would be greatly appreciated.
