I have two sets of chickens; one is 15 weeks, the other is 6 weeks. They have been together since the younger chicks were 3 weeks old (with a special area inside the coop for them). The problem is that the older chickens (5 NHRs) continue to pick on the younger ones (15 White Mountain Rocks and 2 Hubbards). It's not as bad as it was, but I'm still busy spraying blu on bare spots. I tried to separate them within the pen, but either the bigs will fly over the 3' divider, or the littles will go under it -- seems like an unhealthy co-dependent relationship. I can't get it any higher, and the rough ground leaves little spots to wiggle under. Are the Reds old enough to free-range? It seems I read somewhere that they should be 20 weeks. Am I remembering aright? TIA Uh oh. I just realized I'm in the wrong spot. Does anyone know how to move me to the right one?
