Yep, over the years I've acquired young males described as females. They have since grown up and have had to be separated from the 'actual' females, so I have four separated males each with their own enclosure, which is what I didn't really want. That said, one or two of my large females are being such bullies at the moment. Once they've been out in the garden for a few weeks, if they are still being unbearable, it looks like I may have another couple of separate enclosures
I think it's because they are a bit cooped up at the moment. I might try a couple of the males together this summer, and see if they can sort out their heirarchy without killing each other (not literally), if they can't, hey ho, I'll just keep them separate.
