Yes. I agree with the feathering on the feet. It’s strange as this chicken came from a reputable farm and was not cheap. Oh well.12 weeks is an average, not a guarantee. I've seen them come in as early as 5 weeks and as late as 16 weeks. The lack of them visible at this point does not mean this is a pullet.
Agree 100% with ChickenBiscuts, this is a cockerel. Waaaay too much comb and wattle growth for a 12-week-old pullet, plus those huge feet! I really don't think he's pure Orpington either, with that much foot feathering.
