Yes, if grey you can look at them under their wings. If no dots, half way or partial way, it's a male, if all the way up and down then it's a female. Otherwise you just have to wait until they start to change once they start to mature. I am usually pretty good at sexing them.
here is my normal whiteface male-8-ball(trust me his name is very fitting)possibly split pied
here is my hen Angus Lutino Pearl Pied(I raised her at 3 days old) mom rejected the chicks
I have 3 chicks- all will be split to w/f
two have yellow crowns, the other one has a grey crown(possibly pied by looking at the pins coming in)
