My first attempt at a trio went fine until the older female delivered. I had already removed the male, and found mom on the floor with the new kits and her daughter from the last litter at the top of the cage. Mom would not let her handy.
They didn't fight, but when the daughter tried to go down the mom would snarl at her. I just took the daughter out, and kept her out.
I have just tried it again with a well bonded pair and added an 8 month old female. They all got a long from the start, so I was lucky.
5 months later ,June 14th 2010 I found the two females cleaning kits and dad standing at the door. Both moms were wet, and both kits tried to nurse from both moms. They had it all figured out in no time. It was beautiful. 5 days later I put dad back and all are happily living together right now.
Yes I'd try it again, but you really need to know your chins. I couldn't do it with all mine. I don't think
could get scary.
