I have 5 Orpingtons 9 weeks old. One is a bit smaller than the others- had a vitamin deficiency when she was a chick, made a full recovery- I kept her separate from the others til now because she was getting medicated. I started reintroducing her to the other pullets slowly, letting her spend time with one or two of them at a time at first. Then let them be separated by fence. Now I have just finished building a new run and decided to put them all in together at this point since it is neutral territory. The other 4 chase the little one and peck at her. I saw once that one even grabbed onto her back and pulled her feathers. The little one started out really feisty and was chest bumping like crazy and everything but now she basically hangs out in a corner alone and runs away if another pullet gets near her- which they will still go after her either peck at her or just run at her. I am in the process of building a large coop and in the meantime I had been keeping the 4 pullets in a small coop I purchased and the small girl in a dog crate with a roost. I have been worried to add her to their coop since they are already cramped in there Is this bullying or pecking order? Will this chick be part of the "clique" once she gets in the coop? Am I right in waiting to finish the large coop before combining coops?
