I have a flock of 26 birds currently, most are roosters. The birds are all pretty young- 16 weeks old, except for 3 bantam hens. The Roosters that I am referring to in this are Austarlorps, and all but 1 will be culled soon. My alpha Australorp rooster, the one I plan to keep, keeps mating with my poor little Mille Fleur D'uccle hen. Today they pinned her down so hard, she didn't move for several minutes. I went and picked her up and she didn't move a single feather (this bird doesn't let me hold her at all FYI). I layed her in a nest box and trapped the other birds out for now. My best guess is that he keeps trying to mate with these smaller hens is because they are more mature, and actually hold still for him. I do have 6 other full size pullets, and he aggravates them, but they don't hold still for him. I am wondering when this will end? I am scared for my poor little hens lives. A huge rooster could, and may have already, crush the life out of them Any suggestions? Will this stop when the other pullets mature?
