Do I have a rooster?

[Ponte]

3-4 months old.

I have been concerned that one of my three Buff Orpington’s is a cockerel. The comb is much larger , the faces is much redder, the wattle is larger and redder than the other two. On the other hand, the saddle and neck feathers are very round,
The legs are no bigger than the other two and it is the friendliest of the three.
He-she is now 15 weeks so we will know fairly soon.
