A bantam rooster found its way into my chicken coop. We have no idea where he came from but it seems he is upsetting the henhouse, so to speak. Laying is off and the two roosters I have seem intimidated by him. I have put a found ad on Craigslist but no answers yet. He is a cute little guy but too big for his britches, I think. What should I do? I left him out when I closed up the rest in the coop tonite. He has places he can stay to be warm but aside from that, I am not sure how much to keep him out. Suggestions?
