I have three Americaunas (one is Frizzle) from the same brood (born Jan 31) and one Cochin, born Jan 1. The Americaunas all go into their second-story hen house (which is inside their spacious coop) at night by themselves. They come and go up and down that ladder all day long. As a matter of fact, they think it's bed time every time I come out of my back door and then they have to come back out of the hen house and down the ladder when they realize I'm not there to make them go to bed. Babette, my Cochin, refuses to go to bed at night on her own, and although she comes down that ladder every morning, she won't go up it on her own. She just plops herself down in the floor of the coop and we have to relocate her every night. This has been doing on two weeks, since we got them. The other three figured out right away that they were supposed to be in there, but Babette just won't do it. Should I be concerned? Their nest boxes are in the hen house, and since she's the oldest, Babette will probably be the one to use it first, but she won't go in by herself. The ladder is not at a steep slope, and it's something she can obviously use coming out of the hen house in the morning. i've never had chickens before and really don't know what to do.
