My male muscovy has a problem with prolapse. I am sure it is because he is exercising his rights with the ducks too often. But when it occurs, he spins around in circles attempting to preen his rear end, and then the other ducks chase after him trying to grab what I am certain they believe is a worm... Anything I can do to help him not have this problem? (Nothing I can do to help him DURING that problem- he won't let me near him) Certainly this is not a good thing, and I am sure one of these days one of the ducks are going to catch him...again, Is this normal?
