Any ideas on breed and gender of my mystery chicks. *pic heavy*

I got these chicks from my local feed store. Im not sure what kind they are. I thought they were EEs when I bought them but later learned that they arent. They have pea combs and are about 3.5 weeks old. They were in the EE/Golden comet bin but I bought a chick from the same feed store that was in the barred rock bin and its turnin out to look like its actually a black sex link (which they didnt even have a bin for so Im guessin the hatchery either sent the wrong thing or they didnt label them correctly when they came in) so obviously these could be anything. Any help would be much appreciated.

This was them when I first got them

Heres a close up of what the feathers look like.

I did a little lookin around. What about a white laced red cornish? I cant find any pics of them as little chicks but they kind of have the same brown inside white feathers that these have. Are those layers or meat birds? These are growin at the same rate as all the others. The biggest of my chicks is actually my BOs.

Can red sex links have pea combs?

ETA: I also have 2 golden comets which I think are considered red sex links but they have single combs. Thats why I ruled out the idea of these bein male golden comets.

Heres some pics of their combs and another pic of their feathers since they have a few more in now than they did in the above pics.

Feathers. This is chick #1

I dont know if production reds have pea combs. It seems like it would be easier to figure it out if they had single combs lol.
