Hi. I have moved my coop to a larger area and moved all my chickens over. It's a new setup for them but all the chickens (and a turkey) seem to have figured out how to walk up the ramp to the coop at night. All, except one silkie. I find her every evening huddled under a tree and I worry she'll get cold at night. It's getting down to 7 (C), 45 (F) tonight. I haven't trimmed any of their feathers and I notice they often hang out in the coop much longer than the other chickens during the day. Could this be because they have troubles seeing? I haven't raised silkies before. Should I trim all their feathers...could this be the reason the one stays out at night? I go every night and plop her in the coop...she seems content to stay once there but I don't understand why she doesn't just follow her buddies. Thank you for your advice.
