I have a four month old Ameruacana chick who was very close to her sister. About 4 days ago, her sister escaped the coop and was killed by a predator. I have 8 guineas and 4 other chickens who are older but none of them seem to pay attention to the lone ameruacana and she sleeps alone in the rafters of the coop at night and runs from eveyone and every other chicken. Does anyone have any advice for me? When I catch her, I usually hold her and she seems to calm down but she really relied on her sibling as everyone seems to have a pair in our flock.
