Help! Breed & Gender

[YahM]

This chick is 5/6 week old. I got it from the TSC, labeled as Isa Brown. It is growing to be much darker than the others I purchased with it. It has visibly larger feet and short tail feathers, compared to the others, which makes me wonder if it’s an roo? But it doesn’t have a comb, so it’s really puzzling! I know only time will tell, but im pretty new to this, so just looking for any guesses on gender and breed?

Thanks so much! Looks just like a buckeye! I can sleep at night now.
