Please don't kill the messenger. .but...they all look like boy hairdos to me :\ Your Gold Laced (2nd picture) looks like there is a chance it could be a girl still... I'm not an expert by any means, but my girls always seem to have a round crest and the boys either sweeps to the back or is completely wild... the easiest way to tell is look at individual feathers in the crest..if the end of the feather is round, it's a girl..if they're sharp/pointy looking, it's a boy
I am with you their dogs look like boys but the last one for sure is. You can see his waddled comming in which from my understanding is a sure sign for boy. Red behind the beaks and waddles
Thanks guys.
