Oh goodness! Be careful! RIR's can be pretty feisty boys.
This RIR Roo is crazy mean. His chest is completely bald from throwing himself at the fencing of his run tring to fight the other Roos. My neighbor put him in the pen and got him a hen and was gonna get some more. But the RIR Roo killed the hen, broke her neck. So he was going to freezer camp because of his aggression.
Still no sign of the crazy chicken, I hope he stays clear of my yard.
