I bought 4 hens a couple of weeks ago. All of them but 1 have settled in great. The other one is staying in the coop. I'll get her out of there but within a few mins, she's back in. What do I do? I can't close the coop bc I have hens that lay in there. Should I sell her? Trade her for another one? Just leave her be? I don't want her to be stuck in the coop for the rest of her life.
