So I have a Leghorn Rooster, Brahma Chicken, and a Pekin Duck that I've been taking care of, we've had them since Easter.. They have a doghouse with a locking door on it, plus a uncovered run. The rooster is the only one that can fly so he goes in and out of the run on his own free will. Last night I locked up the duck and chicken in their doghouse as usual.. And the rooster chose to sleep in his tree.. This morning when I went to let them out, the rooster had strayed a few feet from where he normally wonders so I thought it odd. I let the duck and chicken out and the chicken precedes to like mount the duck (stand on it's back) and bite behind it's head. All while the rooster (who usually jumps into the run at feeding time) refuses to come near and get his flock back into order.. So I bring the rooster up by hand and the chicken precedes to manhandle him (he's half the size). I of course break it up and have the chicken locked up by herself but I can't keep it that way forever. She's also being much more vocal (I had never heard her make a noise before), I think I may of even heard her crow. I took a picture of the chicken in hopes that someone might be able to tell me if it's really a rooster, or if my chicken's attitude changed for no reason?
