Hi, I was wondering at what age I can let the chicks run around with my hens? I've never had chicks before so I'm not too sure what age I can let them live with my hens. I've got 6 hens that are 6 months-1 year old. They are 2 those island reds, 2 australorps, 1 barr d Plymouth and 1 ameracauna. The chicks I'm looking at getting are 6 weeks old. So how long will I have to wait before I can put them with my girls? Do I need to make a special area for them for now? Thanks so much for the help!!
