ISA Brown chick. Pullet, Roo or a different breed?

Yes they came from a hatchery.

I would agree. After looking closely at your pictures, she looks like a pullet. She has nice rounded straight tail feathers coming in.

I think it's a pullet. They don't breed them to look identical, just to have enough brown that it's easy to sort the "brown" from the "white" ones. And yours are all brown.

Yeah I'd say the light coloured one is a pullet. Those other browner ones.do you have any pics of theirs faces and more body shots. Couple look like they have really big legs.
