First time ordering from Cackle Hatchery and I am so pleased! Ordered the 5 bantam pullet deal and was so pleasantly surprised to open the box to 7! They are so healthy and sturdy! Quick delivery, too. So.....any guesses to what I received? All are feather footed except the brown striped one and black with yellow cap on her head. I'm thinking the goldish ones are cochin reds?
I assume this is what you ordered:
https://www.cacklehatchery.com/product/bantam-female-deal-5/
That page says the possible breeds are "Buff Brahma, Dominique, Barred Rock, Rhode Island Red, Crele Old English, Barred Cochin, Barred Old English Game, and/or Golden Laced Cochin"
Black with white on the head will grow up to be black with white barring. Since you say she has no feathers on her feet, and I can see in one photo that she has a single comb, she must be either a Barred Rock Bantam or a Barred Old English Game Bantam. They have different body shapes, so you should be able to tell which one as she grows. You may also be able to tell by looking at the soles of her feet: Barred Rock should have yellow soles, but I think Old English Game are supposed to have white soles. (If she grows up with body shape and foot color mis-matched, go by the body shape, because it's not rare for hatchery chickens to have foot color that is somewhat off from what it should be.)
I see one with chipmunk stripes: she should be a Crele Old English Game Bantam. That is probably the same one you called "brown striped" and said she has no feathers on the feet.
So that leaves 5 with feathered feet. They must be either Buff Brahma (pea comb), or Golden Laced Cochin (single comb) because all the other breeds on the list have either clean feet (Rhode Island Red bantam) or a very different color (Barred Cochin Bantam) or both.
I think the ones with dark backs and some dark markings on the head & sides of the face are more likely to be Golden Laced Cochins, and the lighter ones are more likely to be Buff Brahmas, but I could easily be wrong about that. I can't see comb type on them in the photos, but the comb and the feather colors/patterns should become much more obvious as they grow older. Hopefully they will become clear then.
I looked at what other breeds of bantams are sold by Cackle, that weren't on the list for that assortment, but it doesn't look like they sex the chicks for any of those other breeds or varieties. For example, the Golden Laced Cochin page has the option to buy male or female or unsexed, but the Red Cochin page and the buff Cochin page do not have that option. So I do not think you have any Red Cochins in this female-only bantam assortment.
