My male is starting to get beat up by his females after a year of living together harmonously through many litters.
I'm probably going to have to feed him off, because he's really getting beat up pretty badly lately, and make sure I don't feed off one of his older sons, so that I can replace him. I'm going to hate the lull in prodution while the son gets sexually mature though.
I think females lose a lot of baby making power after a year or so. Not sure if that's the reason but you may want to consider raising up some new breeding females.
