The EE and RIR are pullets.
I think the rumpless one is likely to be a cockerel with that amount of comb and wattles at 14 weeks.
A clear, top view photo of its back and saddle are would be helpful.
Good deal! Sometimes pullets can get bigger combs early. But I was also looking at its overall lighter color, which is another sign of a male. But what the lab says goes.
The Faverolles is a pullet.
The barred rock is looking like a cockerel to me.
The Orpington is looking like a pullet so far, but these can be slow to mature, so I wouldn't say it is definite yet.
Same story with the Sapphire Sky. So far it is looking like a pullet but things could change.
Both pullets, in my opinion. I think the first is a Starlight Green Egger or Whiting True Green, depending on the source hatchery. The black one looks like a pure Ameraucana to me, but I could be wrong. Might be an Easter egger or olive egger.
Looks like a dark shade of blue to me. I see no evidence of barring to call it blue cuckoo.
Breed is maybe blue Marans, Andalusian or some type of Easter egger.
