help knowing if this is a roo? Pic Heavy

[jdr250]

This is a picture of my 6 week old red sex chicken. He/She has always been lighter in color than all the rest and feathered in much slower than his sisters. I don't notice a big difference in his comb or leg size but his coloring is so much like a red sex rooster.

his whole body

and this is one of his sisters to compare

and another

Any help would be greatly appreciated. I kinda hope he is a rooster

I don;t know much about sex-links... but I think you're right. He does look very LIGHT!

I was almost sure when he started feathering in and was so light, but like I said the thing that makes me question it is his comb looks just like the others no bigger maybe even smalled than 1or2 of them and same color.
Anyone else got an idea?
