My chicks are 6 days old today and since day 3 I have noticed two of my light brahma girls fighting. It starts with some angry stares, then they exchange angry peeps, and then the claws come up and they go at it. I'm not concerned about them hurting each other. The fights only last a few seconds and they're so uncoordinated they rarely even make contact. I just think it's funny that they are fighting for the top spot in the pecking order so early. So far my light brahmas are the biggest of the chicks.
