Thoughts on breeds and genders?

1 is a bielefelder. 6 maybe a croad langshan? not sure

Looking at pictures, bielefelder makes sense, but I can't find that breed on the hatchery site

Chicken two looks like some sort of production breed, RIR, New hampshire red, etc. I am mot great with breeds, but it looks quite like

1- Olive egger (cream legbar x marans)
2- Rhode Island red
3- light Brahma
4- not sure yet, could be an Olive egger or possibly a cuckoo marans
5- same as 4
6- blue marans?
7- same as 4 again

Thanks! How did you figure out number 1??

His coloring is similar to a cream legbar, but not close enough for him to be pure. Also, you mentioned that Olive eggers were one of the breeds ordered.
(I edited my post to just say legbar mix, since your cockerel could be a legbar x marans, but he could also be something else, such as a legbar x welsummer. Both of those crosses produce olive eggers.)
