Quote:I can only tell you my experience. Even after I got a second flock of chickens, the different breeds listed in my siggy, Thor never tried to mate or really interact with those hens. He was content with his brahma girls. So I can't tell you if he was too big for the other girls or not because he never tried. However, my brahma flock includes one bantam brahma, Maggie. Thor never hurt Maggie, nor did he really tear up the backs of the other brahma hens. Only one hen, a LF, had to wear a saddle because something about her she didn't mess with Thor well. I guess the answer to your question would be that if the rooster is gentle and a good "mater" the hens would be fine. With a rough roo or an inexperienced one injuries could happen. BTW, my brahmas came from Ideal Poultry. For the most part, the lights and buffs are definitely hatchery quality. My darks are great though - breeder quality or close to it.
