#2 looks female to me (breast color and comb-- Brown Leghorn males and females have different breast colors.)
#1 I think might be male (comb), but I'm not entirely sure.
Those breeds look very much alike as chicks. They have the same basic color for chick down and for adult feathers. They also have the same color legs (yellow) and the same comb type (single). Of course neither one has feathered legs, a crested head, or anything else that would stand out.
As it...
