It's at a very confusing growth stage. The feathers starting in now wont be the adult plumage. Color and pattern can and will change quite a bit from these first feathers and adult plumage that starts around 14 weeks. Mini molts all this first summer. I could hazard a guess but that's not very helpful. Try at 14 weeks if you can't tell by then.
At this age the comb looks pullet. If I'm seeing it right it looks to be a single comb. Is very tight to head still and no hint of red/pink. 5 weeks is the start of cockerels showing color in comb. It can take a few more weeks for late bloomers. You won't know for certain for a few more weeks. That said, she's got fast wing feather growth (pullet), short no red coloration comb (pullet) and I'd wager if you look at the legs they are thin not honking out of proportion tall trees growing out the bottom of chick. Thin proportionate legs (pullet). It's a girl.
