I have two Muscovy drakes and plenty of hens for the both of them. Mocha my black drake keeps on picking on Sir. Drake my pied drake. mocha tries to start fights, corners him, hang on to his feathers and won't let go, and chases him. Mocha is also very aggressive to the hens as well. Not once has Sir. Drake mated the hens without thier will. Mocha is a whole different story. Is there a good way to stop this or should I rehome Mocha?
