I feel really bad because my RIR always seems to be on top of this one particular hen. Then to make matters worst, when he gets off i have another one who gets her before she can even get up. He is to small to get on her without help!! I also have two other hens who he is so sweet and gentle with. All of the other ones he chooses randomly. I just feel bad for that one hen. She will hang around with them while they are free ranging, but when they go in for the night, she goes to the other coop because i don't think she wants to deal with them in the morning. I don't let them free range until about 2 pm, and i think the poor thing realizes she is stuck with them with no place to run. I even put a harness on her because her feathers were starting to look weak.
