So I really need some advice. I have 5 hens who have been together since they came in the mail when they were 3 days old. They are now 6 1/2 months old. Here is the list of girls.... 1. Betty Australorp 2. Henrietta Red Star 3. Jezebel Red Star 4. Pancake Silver Laced Wyandotte 5. Lulu Easter Egger So roughly 2 weeks age Betty came down with some respiratory symptoms. She had a goose like cough and a sneeze. Well I am new to this chicken thing and I was afraid she was going to get really sick. Since none of the other girls where showing any signs I decided to put her in quarantine in my garage in a dog create. Boy was that a mistake. Well I kept her there one week. When I put her back with her sisters all he** broke loose. I had no idea one week apart would upset the harmony. Until now we had no problems what so ever. Jezebel and Pancake are pecking at Betty, enough to make her comb bleed. I have since put blu- kote on it. Betty is pecking at Lulu. I have since put Betty in the dog crate but inside the coop. I don't know what to do. I have read that maybe i should put the bully in the crate. But really there seems to be more than one. I have been letting Betty out for supervised together time. I am so sad. Prior to this I had complete flock harmony. I so want this back. Will it ever happen again? Do I get rid of Betty? I sure would hate to do that but I cant stand having the girls being mean to each other. I know it doesn't help that it is winter here in MN and they are not getting free range time. Their coop is 4.5 x 5.5 elevated. Their run is 4.5 x 12. So I think they have enough space. If you were me, what would you do?
