I currently have a bonded group of three females, all are around two years old. I will be adding an older kit (she'll have just turned five months old when I get her) in August. Two of my chins have submissive personalities, but the third can be a bit "queen bee" in her attitude. She has sprayed the other two once or twice but they have never reacted other than just moving away from her. Never any aggression, and they sleep together all of the time. I am planning to individually introduce each of the submissive chins to the new chin in a neutral space and watch them. If they are ok, I want to do the cage within a cage method. My question is, should I put the "queen bee" chin in the smaller cage? Or the new chin? I figure from what I read that the chin that I already have should go in the smaller cage. I realize it might not work regardless, which is why I have extra cages. Currently my new girl is living in a "kit colony" and she is doing well. So at least she will have had positive social interaction before coming to me. I'd especially like to hear from those that have experience with 4 or more chins living together. Thanks!
