my barred rock chicks are about 6 weeks old and today i went out to check on them after work and one was dead and rig had set in there is another chick that has a bum eye that is swollen and he is standing off by himself from the rest of them. There is one other chick that is doing the same behavior but he/she/it is intact with no visible injuries. anyone had this happen to them this is the first time i have tried raising this many chicks together. I didn't think the males would be agressive at 6 weeks which is what I think happened. Thank you for any insight.
