I got a new hen about a month ago. She does not get along with my others. (I had 4, but down to two). She prefers to be by herself all day (they free range), and if they are in the coop, she is picked on. She refuses to go in the coop unless I force her. I guess this is why she was given away originally. She wants to sleep in a big holly tree outside my front door. She stays up pretty high, and even wants to be there in the rain. Should I let her? I feel like she is relatively safe by my door, up high, and in a prickly tree. I'm totally at a loss for what to do. TIA!!
