It’s male.
When the vet told us for our first chin that it is male, six months later we brought another male, so that they can be friends. I was wondering how can I make them bond, since they were “two males”. They didn’t get along in the beginning.
And three months after that I learned that our first chin is actually female. So, we have male and female.
We keep them in separate cages, but sometimes when we let them out together - they kiss.
We didn’t want to have two chins of different gender but.. now it is what it is. Love them both anyways.
