I recently discovered that one of my 4 pullets is, in fact, a cockerel. Where I live, roosters are not allowed. Fortunately, I have a friend that lives where roosters are embraced and she has a nice large coop, and would provide a happy healthy life for my little guy. He is a 12 week old Araucana. She has several breeds in her flock. 8 of her flock, including one roo, are around the same age, as we went chick shopping together. She has 3 others that are fully matured. We assumed it would be easier to incorporate my guy while he is still young. When i took him over yesterday, it was heart-wrenching. He was already distraught being separated from his flock and the car ride outside the City limits. Once he was surrounded by his new flock, they immediately started picking on him to determine pecking order with the outsider. He didnt know what to do with himself. In my flock, he was the only "bully," and his aggression was mild - mostly puffing up and chasing with a little bit of knocking the girls down from roosting on feeders. In the new flock, he was chased, pecked, and cornered, sometimes by more than one chicken at a time. We tried to limit it a little to avoid injury, but understand it has to happen too. He does not seem to submit, only run away. Eventually, he was able to roost high in the coop and the others ignored him. It was pitiful. Once they all settled in to sleep, the 8 snuggled together, the 3 mature hens huddled close nearby, and he baracaded himself alone in one of the nesting boxes. My friend reported today that he has still roosted to avoid the others, only coming out to drink or free range once the coast was clear. How much is too much pecking and such to let happen? Would it be better to bring him back to my flock until he is grown enough to defend himself? At 12 weeks, can a new flock kill him? I want what's best for all and need to know how to best introduce him.
