Pullet or Cockerel

[LoSmith]

Is it possible for a pullet to have such long tail feathers? I purchased these two about a week ago from a feed store guaranteeing pullets so I can swap cockerels out but don't want to go to the trouble of raising them only to return them (especially since they have to be separated from the rest of my flock until they get bigger) and start all over. Their combs, hackle feathers, and saddle feathers all look identical at this point (10 weeks old). What do you think pullets or cockerels or one of each? (First 4 photos after the two together has the long tail feathers, last 4 photos has short white tail feathers)

Tail feathers don't indicate gender at this age. Your one with the larger comb is a cockerel and your other may be as well. Give them a few weeks as Brahmas can be slow to mature

Seems too early to tell for sure.

I would say at 10 weeks this is a cockerel

And this one is a cockerel

Also this one is (I believe) a cockerel. The comb is awfully red for a pullet at only 10 weeks.
