I'm not sure if this is the right forum to post this, so I'm sorry if this is out of place. I have a chicken who is getting repeatedly bullied by her two sisters. They have problems with pecking at her and I have tried everything to get them to stop. I have repeatedly removed her and have built smaller coop as a rehab place just for her because it happened so often. So anyway, having realized that they just will never stop ripping out her feathers, I have decided to give her the rehab coop to live in permanently. I don't want her to have to live out the rest of her life alone though. I want to buy a couple more chickens to keep her company. She has a foot that is messed up, and although it doesn't bug her, it does throw off her balance slightly when roosting because she can not get a super firm hold. She is also an extremely docile chicken, so I am not worried about her being aggressive. So I am looking for some docile chicken breeds that can accompany her for the rest of her life. Also, the coop she will be living in is 4 ft by 4 ft and 2 ft tall. She is allowed free roam of the yard all day, and so will the her new buddies. The other two girls have a coop that is 6ft by 8ft and 6ft tall. Their run is 8ft by 11ft so they don't have a lack of room either. Thankyou to all who can suggest some good breeds for me to get. 
Forgot to mention: the chicken being bullied is a welsummer.
