I asked on one of the chicken forums but nobody could give much help. Last fall, my muscovy drake Ivan started singling out my biggest rooster, Stella, to attack. (I think that Stella is actually # 2 in the pecking order but he is the biggest; the top cock is a bantam who is very dignified and generally avoids drama and fighting). I thought it because the duck was raised with chickens and therefore had identity issues. I was able to separate him. Several times in the last couple weeks, my 3 Bourbon Red hens, about 8 months old, ganged up on Stella, pecking him and chasing him. They put up their tails and pretend they're boys. Like Ivan, they had no interest in any of the other chickens/roos, even the ones that look very similar to Stella. They seek Stella out from a group. Tom just stands nearby, looking glamorous, while poor Stella puffed up and did his best to fight off these goofballs. I had to repeatedly shove the hens away, letting them know that I'm the top bird in these parts and they're gonna have to get past me first and they will not win. It took a lot of shoving to convince them to give up. All my birds have plenty of food/space/birds of the opposite gender. This has always happened during free range time. Usually the different kinds of birds pay no mind to each other, though now that I think of it, the turkeys hens, usually one at a time, have spontaneously latched upon a duck to harass and chase. The ducks won't fight back though; they just run away or try to get lost in the crowd. I just discovered a bunch of turkey eggs by my neighbors house, though apparently none of the girls have spent much time sitting. One did for the first time try to spend the night on the "nest" the other night but I brought her home. I always keep them in a pen at night and do a head check when putting everyone to bed. Could they just have crazy confused hormones? I'm not sure what to do. The turkeys have caused pandemonium since I brought them home two months ago just because of their size and general outgoing nature rattling the others' nerves. I adore them otherwise. Getting rid of or eating anyone is not an option. I already have a bunch of social engineering-the turkeys get the chicken pen at night while the chickens are in the coop. During the day, I let the turkeys out, and if I'm home the chickens can free range too. I hate to keep the chickens stuck in the pen because the turkeys are naughty. I guess I could shut the turkeys in the pen, but that's a lotta big poop in a small area. I suppose I may be stuck doing that. Any other ideas? Why are they doing this? Will it pass.
