TSC around me get different batches but ive only seen them carry mallard...pekins...khaki campbells and swedish ducks....
Mallards look like wild mallards...dont lay many eggs...arent big enough for meat ducks...ducklings are black and yellow with a yellow face and black eye stripe.
Pekins are the big white ducks like the aflac duck....good layers...big as in 10 lb ducks...attain 7 pounds in 7 weeks so they are great meat ducks too....ducklings are pure yellow.
Khaki Campbells are one of the best egg laying breeds...khaki colored hens...drakes are khaki with dark bronze heads...ducklings are brown with dark almost black feet and bills.
Swedish ducks are a dual purpose breed...they are black or blue(more like a steel gray) with white bibs. The ducklings and dark or light gray with yellow chests.
If you are seriously looking for ducks, what do u want them for...eggs? Meat? Both? Pets?
If you are serious about getting ducks...go to
www.metzerfarms.com and look at their duck breed comparison page...and check out pics of the ducklings.
Metzers lets you buy males and females instead of getting stuck with unknown sex like at
tractor supply. If you are raising meat birds it doesnt matter what sex ratio u have. If you have two for pets it doesnt matter either. If you plan on a flock of 3 or more for awhile or are interested in raising them for eggs, then the male to female ratio matters and should be 3 females to one male.
In my case my wife wouldnt let me kill a drake to eat so buying sexed ducklings at first would have helped me alot.
Tractor supply ducklings are unsexed...and unless u are trained in vent sexing which is difficult unless taught by someone experienced, there is no way to know what sex you are getting.
