Not sure if this is a leghorn or not.

I bought some leghorns from my local farm store and after a bit I noticed one of them seemed to be clearly getting bigger than the other too and had much bigger legs. I thought maybe this is a rooster and expected to see its comb star to develop more than the others. It's comb is not any more pronounced or redder but it is much fatter on its body and legs than the other 2 and also shorter. Now i'm wondering if maybe I got a cornish cross or another type of meat bird instead of a leghorn. The first 4 pics are the two smaller ones pick 5 & 6 are the one in question and the last three are of one of the smaller ones and the one in question side by side in pick 7 the one in question is on the left its much fatter but also a lot shorter as you can see.

I weighed them all on my kitchen scale and the fater one is 100ish grams more than the other two. The smaller two are 237.5g and 233g and the chuncky one is 345g.

Probably a Cornish cross.
