O.K. enough is a enough. I had 12 baby roos (now about 12 weeks old), given to me and have 6 laying hens and 4 juvinile hens. I started letting them free range a few weeks ago. I let them outof their enclosed run around 4 p.m. and back in around 7 p.m. Well last week two of my liitle roos came up missing, I searched and called and finally one came running, scared to death. Never found the other. Today I noticed around 6p.m. all the little roos in the coop except one is missing, the others run scared when a crow crows. The older hens do not seem to be bothered at all and stay out. Do you think it is a hawk or what? I live on 10 acres and there are lots of woods around.
