Need help gendering these chickies

[talkinboutchickens]

Sapphire gem is definitely a female. White one is a male. Easter egger is a female and the others look like pullets as well but one of the Rhode island reds is questionable:

I will say possibly a cockerel based on the leg size and how tall it is.

The cinnamon queen's legs are suspicious so keep an eye on her/him.
