Red sex links, leghorn probably. The ducklings look like khaki Campbell (brown one) and magpie, but I didnt think TSC ever carried those, this is the second one like this I've seen on the forums though (unless that was you who posted last week, lol.)
Sorry,I shouldn't have rushed it! The white one is likely a leghorn. The colored ones are probably red or gold sex links, and the darker red one could be a Rhode island red but I don't know what they look like as chicks. Other than the white one, they should be all brown Egg-laying breeds
