1st one probobly, comb growth but no redness. Ive only heard the wings are red with boys on most ee. But if yours is black, then most likely yes if more white on shoulders then its a boy. Same with slw. 2nd one is a roo.
These are two more of my SLW (in the middle of the pic, the other two are EE's). The one has a single comb (which I know isn't right for SLW), it's not getting red yet but wattles are showing and pinking up.
