I was told by a friend that I should be able to combined the 2 month olds with my 1 yr old hens now. They have been in the same coop, but seperated by wire. So I tried. I debated on how to do it. I was going to wait until night fall, but I had real reservations about the differnce in sizes and wanted to be there to save them if nesessary. I opened all the doors and chicken yards. I watched like a hawk. Most of the hens were indifferent but 2 were absolutely cruel! So after a couple hours of close observation, I seperated them once again. Am I doing it too soon? Or am I too over-protective? I have 10 heavy hens and 11 babies (amaericanas, silkies, wyandottes).
