We recently moved in to a home with a large coop and outdoor run in the yard. For 3 months I "babysat" the previous homeowners 3 hens while their home was being built. About a week ago they came to get their hens and I was sad to see them go so I decided to get some replacements and start my own flock. I found a woman that had about 150 free range birds and she was trying to thin out her flock. She had several that were born in early March (4 months old) and several 1-2 year olds. I chose one 4 month old and 4 one year olds and was on my way. I asked her before choosing my birds if they would have problems going from full time free range to part time free range (in the coop part time and in the yard part time) and she said no. I also asked her if there would be issues establishing a new flock with these birds that may or may not have been familiar with one another and also range in age. She said there would likely be some initial pecking order issues but that would sort itself out over time. The 4 one year old hens are getting along just fine but the 4 month old (easter egger) is being traumatized by a RIR (1 year old) so much so that she will not come out of the coop. I have been bringing her food and water in the coop and checking her in the morning and evening. She seems to roost fine with the other birds but refuses to socialize with them during the day and won't come out of the coop. I am worried about her getting enough food and water and also about being cooped up all day in the dark. I have considered getting her a companion of the same age but I am worried about doing that now, a week in to establishing my flock, and further disrupting the pecking order. Should I give it some more time and see if it works itself out? Should I force her out of the coop? Should I remove her or the RIR all together? Shes a sweet bird so I want to make sure I give her everything she needs. Any suggestions?
