Identity and sex please 6 weeks old pic heavy

the blck and white where i cant see the front of it loos aracana or exhecater leghorn.(cant spell) first few look like golden laced something. have no idea on others

the first one and the brown /black sitting with the black/ white look like roos

I think pics 1 & 2 could go either way but I guess the comb isn't really large so i'll say pullet and possibly golden-laced wyandotte, pics 3,4,5, & 6 look like EE pullets, pic 7 looks like a roo in the back and maybe an EE, and pic 8 looks like a pullet and i'm not sure about breed.

Are these all different chicks or are there some different pictures of the same chicks? Labeling would be helpful.

DISCLAIMER: I'm not familiar with any of these breeds, just exercising the knowledge I've gained.

If the breeds you mentioned were the only possibilities, I'd say the first is a roo, probably barnevelder; is the chick in the pic with the B&W the same or different? Also looks like a potential barnevelder cockerel.

Not sure on the wellies/leghorns... welsummers will have red earlobes and leghorns will be white. I'm not sure if one is yellow skinned vs white skinned. Google Image search turns up both leg colors for both breeds. The adult color is very very similar, but the body shape will be notably different. You may not be able to tell the difference for another ~6wks until earlobes come in, or maybe your leghorns will start growing their combs earlier (both male & female have huge floppy combs at maturity, so don't go throwing any of those in the freezer before you have good evidence for roos). Good luck!

The white looks like a breed standard ameraucana pullet (someone correct me if I'm wrong) - KEEP HER!!! There is no green in those legs. She should lay a beautiful blue egg.

Wyandotte is not an option here. Of the possibilities, barnevelders are penciled so that chick is probably a barnevelder.

The lighter brown ones look like Welsummer pullets. The top darker, brown bird could be a Welsummer rooster.

TOO CUTE!!!

I think you barnie is a roo.
Leghorns are supposed to have yellow legs and white earlobes. Their leg color changes some while they are young, but they are all pullets, so it would be a good idea to hold onto them until they are 3 months old so you can tell them apart, if you can.
Your black/white chick looks like an ancona or exchequer leghorn pullet.
