For a while there, I thought I had the nicest bunch of hens, really welcoming and kind to new chicks, but I was wrong!! Me and a friend traded chickens, and what she gave me: a 19 week old Australorp hen. Who is currently getting her tail whipped by my EVIL hens! Also 18-21 weeks old! If It helps, she is in the coop with the Barred Rocks, the RIRs and the Araucana. I have had so much success with the 'roost by night' thing, I'm shocked! What should I do??? Right now, she is in a separate box, within the enclosure, and they are swarming around the box and jumping on it!! HELP!
