Pekin or Aylesbury Duck?

[duckduckgoose13]

Hello everyone! I just had a quick question on the breed of ducks that I have. I have two what I think are female Pekin ducks, I ordered them from Metzer Farms. I got them when they were about a day old and as soon as I opened the box one had a orange bill and one had a pink bill but I figured maybe sometimes bill colors vary because she seemed to be healthy. As they got older I noticed that the one with the pink bill started to get more fat and overall bigger but I just thought that maybe she was growing faster. Now that they are about 2 months old, I notice that she is more built like a box/boat shape with shorts stubby legs, and little ground clearance and my other one is more upright and thinner? They both get fed plenty and one isn’t fed more than the other. Do I have an Aylesbury duck and a Pekin duck or just a big Pekin duck?

Pictures of your ducks would help duck people tell you for certain. :]
