No other girl. I put the 5 I have now in with 2 girls I had a few years ago that died of old age. They didn't get along. They pretty much tried to kill each other so I had to keep them in separate pens and couldn't let them out into the yard at the same time. I also tried putting some goslings in with them and they were really mean to them. When the goslings were full grown I tried again and the same thing happened. So I've given up on trying to put them together with any other animals. They don't seem to tolerate any other animals other than those within their group. And sometimes they don't even get along with themselves. So getting another girl wouldn't be a good idea.
I can understand why now them girls can be something to reckon with. lol
