I have my bins set up all next to each other, with uno in between two girls. He's been tearing up his cage every night and i bet its because he wants to get to the girls. Should I move him to the ground ?
Ditto what Nancy said. My boys have never had a problem being around girl smells. They sometimes get excited over it, but never really beyond some serious air-sniffing and running in circles. They all act the same at night.
Ditto to all of the above. The only time any of our boys react is sometimes if they're taken out right after girls and put into the playpen (especially if one of the girls has peed, haha), or sometimes if we don't wash our hands after handling a girl, one of our more girl-crazy males might be especially fidgety. When it comes to just housing them near each other in the same room, they might as well be on different continents.
