I'm getting really nervous about one of my birds, gender wise so I subjected her/him to lots of pictures today. This is a 20/21 week old bird who was suppose to be female but now I'm just not sure. This was the smallest of the chicks, also the loudest from day one but the friendliest too. The other two are bigger, but have no crown to speak of....very small. I wasn't sure which angles would be the best so there's a little of everything. Any help is appreciated. Thanks in advance!
