Hi Krista!
The 2nd one is almost certainly a girl. Yaay!
The first one is tougher --- those wattles can be deceiving.
It still has a nice tidy, pale comb, tho, so I'd *tentatively* say girl.
By 7 wks here I can tell definitely. Pics are tougher, because sometimes it's stance and attitude as much as combs/wattles.
