I have a RIR rooster 3 times the size of my bantom Old english. But the bantom is the one that crows, and protects the flock, I was letting them roam tonight and a deer came out of the woods about 50 feet from them and myself. and that littel bugger started heading toward the deer with a balk here and there. The deer didnt seem to be to worried LOL. But he just worked his way across the yard it was halarious. The rir was the most agresive when they were chicks I figured he would be the domanant male , but I'm thinking I'ts the bantom!!. Why dose'nt the RIR crow? , and will the RIR mate with the large birds? and the bantom with the other old english bantom that I have? also do I need more bantom hens to take care of him? Thanks for your help. I'll post pictures of them tomarro.
