I have 13 chickens in my basement..... The first 6 are RIRs and area week older than the other 7. When i try to feed the RIRs there is one that will attack me. I am all pecked and scratched from this one bird! I generally give it a backhand and send it sailing across the pen when it attacks, but geesh, this is getting old. The RIR were a straight run and the guy who picked them for us used an old farmers technique for get hens...well I am thinking this one is a roo. What can I do with this bird? He makes me almost afraid to stick my hand in then pen to get the feeder to refill it. Now, some of the other RIRs are sweet as pie. One will follow me around when I am cleaning the other half of the pen and lets me pet her...but this one....wow..... I think he is still a little small to be butchering....11 weeks old. I am hoping things will calm down once we get the coop finished and get them out.
