It not for its head and feet, I'd say its a duck! Ha! Still not sure if its a hen or roo. 20 weeks old. No crowing and no spurs.

It's a late developing cockerel and a hatchery type Leghorn or Leghorn mix. Or maybe a California white.

I vote with @The Moonshiner . This man knows his birds, so I go with his decision.

It is hard when you have no sibling to compare it to. I am not sure.

I don't know, the sickle feathers look round but the hackles look pointy.... but then again....it's feet are huge...
I don't know..... I want to say pullet.... but....

I just realised I never finished my sentence. What I was going to say was...I think it's a cockerel....

 

[Texasclucker]

What do you think?

Hmm, what a confusing bird! i see where everyone is coming from with their guesses maybe it doesn't even know what it is! i see shiny neck feathers and the shiny saddles on its back but its face looks hennish in one picture how weird i think i'll go with cockerel though

 

[InterestingChickens]

I do see the saddle feathers coming through. As for the breed, a production based White Leghorn. A hybrid somtimes called a Star White.

He was a single hatch

He/she was a single hatch. I wish there had been at least one more so he would have had a friend. All the other hens have made life hard for him. But has finally starting defending itself.

Going out on a limb here....
Not a pullet
Not a cockerel
It's a

DUCK!
