Buff Orpington - pullets / cockerel(s)?

[ColtHandorf]

In this image, the cockerel is the one furthest in the back. No ifs, ands, or buts. It's not a "masculine pullet". It's a male.

One cockerel and the rest are pullets.

Those birds are 14weeks old according to the op which means 3months and 2weeks
Even if that was a slow maturing roo it's comb is meant to be more than that
In this case I believe it's just a dominant hen
I had one just like that, thought she was roo from the start, until it was obvious she wasn't

I think this is a classic case of wait-and-see. Five are for sure pullets, but I think that one in the back could go either way. Buff Orp cockerels tend to be very obvious at a young age, so either that’s a slow developing cockerel or a fast developing hen.
