Who likes the guessing game?

[Adnammi]

I have 9 5 1/2 week old RIR chicks. 8 of them are obviously pullet or cockrel but Nugget has me stumped. The first pic is Nuggy, 2nd is obvious roo, 3rd is obvious hen. Guesses?

I'm guessing boy. Just slower to develop wattles.​

Roo

He's definitely a cockerel

I think so too but thought I'd ask people with more experience. I'm new to young chicks.
