Alright my SFH that I was 100% sure was a pullet is starting to worry me. You guys said she was a pullet at 7 weeks, shes on the left

And now at 13 weeks, she grew into this overnight.

'She' has about 4-5 copper feathers on her wings, but not the shoulder area which is the typical spot for copper feathers with roosters, and low on the back of the neck 'she' has some copper 'lacing' on 3-4 feathers. 'She's' also has wattles coming in. This has all happened in the last week, week and a half.
Is she a fast developing pullet, or slow developing cockerel? I've never had a pullet this age with this much comb before with all the different breeds I have had.
