She or he?

The plot thickens with my chocolate wyandotte bantie chick.  12 weeks old now and red comb but not overly whattly.  If it is a boy the breeder has already said she will have him back (unless anyone on here wants a swap???)

I've been looking back at old piccies of my Serama boys and they were much more developed at this age, so confused is not the word  What do you chicken experts think?





Will be a shame if its a boy as the 2 chicks have really bonded    This is them on their first garden outing this weekend.   The other one is a blue orpington bantie.

Cockerel.  Bantam dottes don't develop very large wattles.  My two boys last year didn't fully mature until about 28 weeks, and neither of them had big combs or wattles.
