I received my chicks from the hatchery this morning and they are doing great so far. I was in just a bit ago to check on them, and noticed that 1 in particular is being really mean to the other chicks. She ( supposed to be ) is grabbing all the other chicks by the hair under the eyes are pulling them all over the brooder! Is this normal?? Is this just them establishing pecking order, so to speak?? Do I need to separate this one from the others??? TIA for your help on this!!
