Yea I was having problems at first about the RIR picking on the polish birds but, since I have started housing them an the silkies together no problems have came up. Today I had a Dominique die I just got them Saturday night my supplier told me they had a cold because of our crazy weather here hot then cold. I have been medicating them they seemed to be fine then two hours later one was died they are only 10 weeks old. Any advise they are separated from the larger birds because of weather conditions an size?
