Tractor Supply chicks, what breed ? All it said was sexed pullets. I really didn't want a rooster so

Actually, the Red Sex Link requires the rooster used to be Red over a silver(white) hen.

OP- these are likely a red laying bird, of some kind. The odds of getting a true New Hampshire or true Rhode Island Red from a hatchery are longer than winning MegaMillions.
They will likely be great layers and happy, healthy birds and that's about all that's important.

It does look like a Golden Comet, I have 4 hens & love them. So easy to work with and this year I only had abut 20 times I only got 3 eggs instead of 4 daily. Good luck.
