I have four GLW we hatched and three are lighter in wing and not feathering as quick. The dark one with feathers also seems to have smaller darker comb. Am I doomed with three Roos? Dark GLW
To be completely honest, all the chicks that I can see have big combs. Now this could mean you have all cockerels OR ,if they all have the same parents, that they are just naturally large combed and it really isn't as great an indication of gender at such a young age. Now that said, the rightmost chick in the first pic looks likes a cockerel, it's very red already.
I agree.They're too young to sex accurately, but if I had to guess, I would say all are cockerels.
