I started my flock with 3 hens. After we moved 2 got out of the coop and we're killed by my dog, leaving only on (she is a large barred cochin). She was never bossy or noisy when there were 3, but now she's out of control. If she hears me flush the toilet early in thr morning she starts squawking. She's almost noisier than a rooster. I live in a suburban area, so I need her to not be as noisy buy I'm not sure how. She'll even be noisy if she has food and water. I can't let her free range as much as I'd like because of my dog. But they were never able to free range daily even before the dog attack. She has also been attacked by my dog, but I nursed her back. She just had some skin and feathers get ripped off and she healed quickly. Now here is what I struggle with the most. Once the other two chickens were killed, I got 4 chicks (americauna, black sex link, golden sex link and blue cochin) so that we could continue to have eggs. The coop situation has been fixed, so the dog can't get in at all and the chickens can't get out. The pullets are about 3 months old now and have been outside for about a month in their own run right beside the hen's coop. My first 3 attempts at introducing them has failed. The larger hen has attacked at least one pullet each time. Today I tried it while they were free ranging, so they had plenty of room and their own food and water. I don't want to rehome her, but I'm at a loss for how to.get them to get along.I thought having them side by side for a month would help with integrating them, but it hasn't.
