Im relatively new to chickening and need some advice. I have a good size coop and run with 9 two year old laying hens and one BIG but gentlemanly rooster. This spring I bought 10 more laying hens that are currently 9 weeks old. They are all feathered and doing well and have been in the coop, SEPARATED from the big kids, for three weeks. All is well. Ive had a few escapes by the teenagers into the big world, with no ill effects. But Im worried that the older birds might still hurt the new ones. There is a size difference that worries me. And especially "Big Roo's" interest in the new girls! Can I get suggestions on integration ages and procedures? Thanks!
