The white one looks like an ameraucana. Does the lavender one have green legs? Might be an EE. The buff silkie will be quite "dirty" in the tail and wings - it may be crossed with blue or partridge based on the foot fluff coloring.
Is the grey/blue one a blue splash, or lavender or ??? She's my favorite
Her name is Sassy, because....well, she is! She DOES have green legs, and the white one does also.
I kinda thought the black ones (we actually have two of those) were probably Plymouth barred rocks...they are just so much smaller than the others and developing more slowly, I wasn't sure if they could be something else?
The silkies....one was a partridge colored chick as a baby (I mean she had the definite striping on her back) and the other actually started out as a light grey chick.
The one who is a mystery is the multicolored brownish one. She also started out being "stripey" on her back as a chick, but they were fainter stripes than the silkie. She's definitely the largest...we are calling her "Big Mama".
