I only have this one which I don't know is it male of female, and I have option to get female or male just now and would like to have a pair. Thanks in advance for your reply.
IMO, this is a difficult one. If you look close, you can see the blue bearding coming in underneath the chin. However, the forehead slope and overall shape looks more male. I'd say give him/her another month or two and it will be much more apparent.
