I have had many breeds of ducks, but these are my first pekins. I got them and 4 other ducklings at a feed store in April. I know they are Pekin, but they are HUGE. Since I've never had them before, I can't compare them to anything else. Jumbo or regular? They were so big that the kiddie pools weren't deep enough for them, so we caught some 60 inch round ones on sale at K-mart for 9.99. They are about 1 1/2 to 2 feet deep, and they can actually float in them and not touch bottom. They love it!
