I followed all the rules about introducing her to the 3 big girls in the coop, it did not work. She lived outside in an adjoining cage for 8 weeks, in the coop in a cage for several weeks at night and I introduced her in the middle of the night. They pecked her so much today she got bloody so I rehomed her to my sister who has more room and only free ranges. She is now happy. History- these 3 big hens killed 2 8 week old chicks (her siblings) I am rehoming the 3 big girls this spring and getting 6 new baby chicks.
