What breed are my chickens?

[Star silkies]

Your pretty orange girl is Isa brown. They are fun friendly hens

And as I mentioned the tractor supply chickens are like that. Meaning the comb is not right by your standards but fine by theirs

The white ones with the black spots look like my neighbor's california white chickens...they have that rusty coloring on their chest also, which she that was staining from their feed and water, but maybe it's actually their feathering.
