I've got 6 chicks that are almost 3 weeks old. They were all purchased from a feed store the same day at a few days old. One of them is pecking at the others, damaging and removing feathers and making them cry out. I don't think it's far from drawing blood. This is not my first round of chicks, but I've never had one that is so aggressive. Theoretically its an Easter Egger pullet. The constant crying of either the aggressor mad at being separated or the pecked on others is making me crazy. I'm leaning towards trying to return it to the store tomorrow unless anyone has any better suggestions or hopeful stories of chicks turning around their behavior. The only other idea I really had was just to put it outside with our 2 month old chicks, but that seems cruel.
