Which breed and gender is this chick?

[Meganschultz]

I have what I thought was an isa brown chick but I'm not sure. We were gifted six Isa browns six weeks ago and we have three that are this darker color and three that are much lighter. They are all the same size. This is the one that has me stumped. Its tail feathers are very short, there's no pronounced comb or waddles, but the legs are thick and massive. Thank you in advance. (P.s. this is one of my first posts and I'm not sure what the "hatching" means at the very top
