I bought five chickens a few months ago. Two older hens, one young hen and two young roosters. We didn't know they were roosters. One of the older hens was getting attacked and I separated her and got rid of the aggressive rooster. The hen went back to hanging out with the other three chickens for a week or so but now is scared of them again. They free range during the day but she is hiding under a bush because the other chickens (mostly the rooster I assume) are out and she is scared. The place I got the chickens from has 30 chickens or so and the lady said I could return them if I needed/wanted to. Would I be better off sending the rooster back or sending the old hen back? I wouldn't want the old hen to just get attacked if I gave her back. Thanks.
