Okay I but some chicks outside the coop in temporary intro pen. My Black Giant Jersey seems to paying a great deal of attention to them, on day one he just stood there and looked at them (he had never seen 12 wks old chicks before ) for an hour before everyone was put to bed. Day 2 him and 5 orp hens are now watching over them. I m not sure if they want protect them of kill them. Needles to say I m not ready to mix to gether yet. Day 3 Put 10 wk old chicks out to get fresh air and guess whos there. "T" yep he noticed the new babies and is now on the job. Whatever that is. What do you guys think.
