Does anyone know what these are?

[blorbs]

Sorry if I did this incorrectly I've never used this website! Anyway, I know nothing about chickens or about these chickens, does anyone know what they are? They were already different sizes when I got them, one of them has grown a ton and the other hasn't grown that much. Is the big one a male? The red patches on the big one are new, it looked much more black and white before. I've had them for like 3 weeks.

PS the cardboard box is in there because they like it, and they have an actual feeder and water thing in their little area/run thing, this is all just extra stuff out here. but if there's something that looks super wrong please let me know because I've never had a chicken before and I truly have no idea what I'm doing.

EDIT adding a picture of the small bird (total of 2 chickens in this situation):

One is a cockerel, in the last two photos

Hatchery Barred rock? @Overo Mare

Both are male, sorry.

Look kinda like black sexlinks males

You are correct. The lightest (lightest one with the red patches) is a cockerel.

The second one could be a slower developing cockerel. Hard to say for sure without knowing age though.

That's what I was afraid of... I should probably get better pictures of the other one to make sure it's a girl. Thank you!

If they're black sexlink, they're definitely males due to the coloring, right? Because of genetics? But is there anything else about the small one that says male? I'll go get a better picture. I meant to get 2 females!

I am thinking its a pullet, but waiting for pictures!

Welcome to the forum and to chickens!

Do they have a solid structure (coop) to go into for sleeping and inclement weather?
