Are these Jumbo Pekins?

I got them as eggs being told that they were pekin, but looking back at pictures of my old pekin hen they seem pretty fat lol
The two on the straw are my current two, considering their quack I’m guessing the one on the left is a drake and the other a hen. The other two pictures are of my past pekin hen. Let me know!

Very pretty hard to judge size from a picture but they very well could be Jumbos. Be sure to keep them on supplemental niacin [Nutritional yeast] So they don't develop a Niacin deficiency which happens a lot in this breed
