My 2nd chicken died today, let me explain. I had 5 young chickens bout 7 weeks old, then i got 4 young chickens but older than the others about 14 weeks old. Over time, 1 of the older 4 took alpha hen position of the flock. 2 of the young 5 turned out to be roos. Now ive had them all for 3 months they are at an age where the roos are getting their feathers and looking and acting more like males. (Also i understand my roo to hen ratio is out of whack with the 2 roos, dealing with that soon) is it possible that the roos got violent with the alpha hen to take leadership of the flock?
