We have a nice new (to us) coop for our 2 older girls. Now, how would you go about getting them in the coop? They are so flighty and don't come easily to treats. Also, once I get them in there, should I leave them in for a couple of days? I'd feel horrible doing that. There is no run, I usually just let them lose in our fenced backyard. It's probably about 10 sq. feet inside. Ideas, thoughts, opinions? What has worked for you?
