Very large chick??

[bleu]

Hi, Im new to this and am incubating some eggs for the first time in 25 years but couldnt wait so I got some chicks from the feed store. 2 RI reds, 2 Ply Barred rocks, and 2 California whites. They are all growing fine, but 1 of the Cal. Whites is just "giant". they were the same size when I brought them home. This chick has alot thicker legs, bigger feet, just overall big. Just wondering if chickens can suffer a sort of "Gigantism", I know it sounds wierd but I just wondered.

It could be a male and it could be a meat type birdie that got mixed in by accident. Were there any meat birds in the feed store?
