With all of mine I have never had them to really fight, they play fight all the time, until Jasmine went into heat, her & Blossom would fight for no reason, now that Blossom is in heat they are fine, Its funny with the girls, I only had the one girl for the longest time Lexie and no problems with the boys, now I am waiting for Tarra to go into heat for the first time, I am really thinking all hell is going to break lose with that one, she is my wild spirit
Hopefully things will calm down for you, is the one not spayed going into heat maybe
