I have recently been pulling out my hair over trying to introduce two bantam cochin pullets to my flock of standard birds. I have had the 10 week old cochins in a cage inside the hens' coop for about two weeks now, and there seems to be no improvement whatsoever. The big girls seem determined to peck at the little ones, no matter how many nights I put them in together on the roost, or no matter how many days the babys spend in the cage in the coop. And it's not a dominance pecking, it's pecking for blood. This behavior spreads even when they're free-ranging. The babies stick close to the house and to myself (I only let them mingle when supervised). The bigger girls will be all the way across the lawn, then it seems that they randomly decide to murder the babies, and come over to chase them and peck them. The cochins are in no way challenging their dominance, or the pecking order. They do nothing to defend themselves. I'm starting to be at my wits end, there is no one instigator. The entire flock is in on it. What am I missing? It has to be possible to intergrate them. Please help.
