I have the same problem with my males.
They will not get along in the same room as the females.
It can get pretty bad when she goes in heat.I have read that some will fight to the death to get at her.
Then on another list I was told that's not always the case, and males can be housed together without problems.
Now if someone would tell my chins that.
I'm always going to give it a shot, and have 2 brothers now that I will try to keep together or maybe one with Dad.
I have much better luck with opposite sexed pairs than same sex.
You can move the female as far away as possible and see if that helps.
Put one of the males with the female, or split the boys up.
If one of the males are plucking fur from the other I'd split them up.
It could cause too much stress on the fellow getting picked on, or worse.
I do hope others have some tips, I could use some too
