I'm co-chickening with some neighbors w/ my two rhode island reds (who are 4-5 months old) and their chickens that are about 2-3 yrs old. One is a banti (sp) and the other is Maybe an Orpington? It is our dream for them all to live happily ever after in a 6x 15 coop/chicken run w/access to a larger area by day. My little chicks lived in a modified dog crate until about 2 months and then we put the dog crate into the big coop w/the older chickens for about 2-4 weeks with a barrier between them, two different feeding areas and water areas. After 2-4 weeks we took the barrier down and letting them all live together and establishing the pecking order. At this point they're all about the same size and the Orpington is the lead chicken- she pecks at the others and gets her Banti friend to block w/her food areas, water dishes and laying boxes. Even before my chicks were introduced the Orpington was displaying "rooster like" behavior- cockadoodling.. bigger comb etc. We sprayed the Orpington every time she was mean to the chicks and we were around. As of the last few weeks the Orpington has stopped laying eggs (before she was a heavy layer and now i think it's been a week since she produced) and is loosing some feathers (a lot around her neck) no one is pecking her and if anything she's the bully in the roost. It seems like she's extra stressed- or perhaps it's just mid summer molting? Is there anything we can do to help her out or will this all just blow over? Should we separate them again- let them work it out? We're not sure at this point if anything should be done or just if it'll get worked out. Any advice would help!
