Can't read the feathering (saddle & hackle) yet but see the comb/wattle has developed though not much color, still thinking probable Cockerel but post pics in a couple more weeks.
I have some who are about 2 1/2 months old... by that age they all had really long tail feathers and they are pullets. The boys take longer to feather out than the girls. I agree with @ChickNanny13 that in a couple weeks it will be easier to tell for sure.
