What breed is this and sex too please

[kat79]

Hey I got some chicks from a hatching programme but they were not sexed and I have no clue what breed they are as I only had leghorns many years ago their about 10 weeks of age

On both pictures I see Sex Link boy.

****!!! So it is safe to assume then all the others are roos too? so is it safe to assume this maybe a pullet then?? Sorry this whole sex link chicken thing is all new to me

If they're sex link, then yes, the whites are roos and the reds are pullets.

Not sure to be honest....I got them through a school hatching programm and really didn't get any info at all
