Hello!
Could you please help me figure out if I have pullets or cockerels?
These are my first silkie chicks, they are 8 weeks old.
Chick 1 - Betty - White Feathers red face
Chick 2 - Johnny - White Feathers, grey face
Chick 3 - Meryl - Grey splash
Chick 4 - Edna - Black

Any help would be wonderful

Thank you!

How old are they? Not sure about the black but they all look like females to me (the black i would lean more toward female but depends on the age- comb is a little larger and the lack of filled out crest (although could be nonbearded) are more male

At 8 weeks with bright red comb like that chick 1 the white on Betty is defo a cockerel nt sure about others would need more close up of face and comb x
