Silly looks more like Phyllis....................Diller, that is, to me! I can't offer any male/female advise, but just had to comment on the resemblance.
I'm still debating on Polish myself. Maybe if I opt against them this year, I can be a polish mom vicariously through you?! LOL
I'll take a wild stab at it just for fun. I think Phyllis is adorable but I lean towards boy. Though it's really too soon to tell. Silly looks girly to me.
My Polish rooster had wattles growing by 7 weeks, they were tiny but still I could see them. The girls didn't have any until way later.
Wild (and wistful guess) but I'm gonna say two hens. If you look at the ends of the feathers in their crests, they look round to me which makes me think hen.
