We apparently have two female and two male muscovys. They freerange a little during the day and I lock them up at night for thier own protection. I've noticed that they are starting to mate the females. Okay here is the concern. One male had a female in thier pool and he had her head underwater for a loooong time. I broke it up because I thought she might drown lol. She didn't act like she was gasping for air or anything and swam around like nothing happened after that. So should I worry about this behavior or not? Also, I just read something about not being able to keep adult muscovy males together in the same enclosure once they are mature because they will fight. We are eventually going to have to make a large pen for them because they don't always stay in the yard like they are supposed to. Does anyone else have more than one male together once they are mature?
