We adopted a lonely hen 10 days ago. She was used to being free range. I have a roo and 3 hens already (free range). I have quarantined her in a makeshift 6'x8' covered pen with roosts, a carrier (night time home), a dust bath, etc. She has escaped 3 times, I think it is finally escape proof now! She has only given us one egg (day3). A few days ago, I noticed feathers lying on the ground under the roosts. Everyday, there are more! I think she is stressed or bored being cooped up so she's plucking herself! Should I just let her out to mingle with the others, hoping she comes back at night? Each time she has escaped she gets picked at by the oldest hen (hierarchy?). As soon as I realize she is out, I get her back in the pen. Thoughts?
