The bird in question is ((JG x RIR) x RIR) x Rudd Ranger. There is no telling what lines went into the Ranger. But his father, g-father and gg-father were all chosen for good behavior.
I knew someone was disturbing the flock, and I suspected him because the senior hens were avoiding him.
I heard one of the chicks (12 weeks?) screaming. He would mate with her, let her run, chase, pin her down, mate, chase, etc. With her screaming the whole time. He was treating it like a fun game. A good dozen grown hens and pullets around, some of which did let him mount, and he goes after a chick. Her comb hasn't even started to turn pink yet.
He's in the bachelor pad for the duration. She's still injured and struggling to walk.
