I can not be sure and I have already rained on one persons parade today.... It would be easier if he/she was standing next to another one...BUT
If you keep in mind I am far from an expert on this, I would say there is a good chance. He seems to have stout legs for a girl, maybe if you had he/she wearing high heels they would look more feminine. BUT that tail may need a little trimming before she/he tries on a bikini. sorry,,,, either a boy or a very masculine girl in my untrained eyes.
Hens go broody when you don’t want them to… and won’t go broody when you do.
Have to add, no matter what it is, it's super cute.
