I have a flock of about 30 dual purpose chickens. 25 are standard size, 5 are bantams. 1 of the 5 bantams is my sole rooster. He's a Barred Rock, I call him "Tiger". Just like Tiger Woods, he's black/white with an addiction to mating.lol Tiger is rough on ALL the girls despite his size. I feel like he breeds every chicken multiple times daily. It just seems so excessive...! The hens can't even grow feathers on their back. Aside from that, multiple times in the last few weeks, I've witnessed some behaviors that I had not seen before. For as dominant as Tiger is, he is being mounted and appears to be being bred, but on the receiving end, by a Bantam Rhode Island Red HEN! They make it look so natural...! What actually is going on here? Why submissive to this one hen? Even more puzzling, is the Hen that mounts him seems to be at the bottom of the pecking order. Is my rooster broken...!?
