My TSC got chicks this week (in KY) and they got some golden comets, white rocks, and something else..black sex links? They also got pekin ducks and mallards. They said you have to buy ducks in groups of four and chicks in groups of six, which is no good for me....
You should call your local store--I called 3 of them around here, and they were each a bit different. They were all getting chicks the week of 4/5, but one said that they only got straight run, one said that they got mostly RIRs, and one said that they sometimes had sexed birds, and they got an assortment, no idea what kinds. Last year, I know one TSC wasn't doing chicks at all--so it's best to check with them and see.
