Production Red or Red Sex-Link? Gender?

[FernHill]

purchased some ‘RSL’ chicks from
Local farm store because we can’t have roosters. They are 5 weeks old and look a lot more like production reds to me based on what I’ve seen in photos. Also one of these is not like the others- darker feathered, darker beak and larger comb. Any help appreciated.
First 3 photos of the suspected cockerel. Then of another in the group for comparison.

To young to say for sure but I think your suspicions are correct. They look like Production Reds.

Thanks, fingers crossed they are all pullet, but annoyed that I ordered RSL and pretty sure I got a non sex-linked cross

Yes, they are either Production Red, or hatchery RIR. How old are they?

5 weeks

Updated pictures at 6 weeks just for fun. Going to stay in wait and see mode for a while regardless but interested to hear any thoughts.

A few more photos at 7 weeks, darker bird is the one we think might be a cockerel

Another couple photos at 8 weeks.
You can see the comb and wattles are still much more developed on the darker bird than the others. We have no idea pullet or cockerel

Updated photos at 10 weeks, the one with the comb and wattles is the one that we can’t figure if it is pullet or cockerel. That it stands apart from the obvious pullets a lot of the time (see photo) pushes me to think cockerel
