The injuries look small enough that they should quickly heal on their own, but it's worth trying to figure out how it's happening since multiple chicks have the same injury in the same place. I would suspect there is something sharp somewhere that is poking them.
Pricing can vary quite a lot by geographic area, age of hens, and the quality/condition/transportability of the coop. In my area I see folks occasionally post about entire flocks of chickens, sometimes including coop and supplies. You could try offering up the entire package at a special price...
Suspecting a cockerel seems reasonable, though of course time will tell. The best way I've found to prevent chicks (or adult chickens) from picking on each other is to provide more space.
I vote pullet. Barred rock males have more white barring. I also don't think the comb looks too red for 10 weeks. Of the breeds you mentioned, barred rocks are the only one with a straight comb so it will look more pronounced regardless of sex.
This article is incomplete! I mistakenly thought it would save in draft form rather than publishing it right away. I'll try to finish it up in the next few days. I need a bit more time to get the photos and other media I want to add.
As I write this, I know it's a controversial topic. This...
Thanks for checking in! I am well, just busy with other life stuff including getting close to earning a PhD, house things, travel, etc. I'm still a chicken-keeper and just got some new chicks. I check back on BYC every once and awhile. Who knows, I might get more active again sometime. I hope...
I have a backyard flock, including a 2.5 year old wyandotte whose feet are pictured below. Note the nail overgrowth and raised scales. She's the only bird with overgrown nails, everyone else's are a much more normal length. Their run is large and they spend plenty of time scratching.

Welcome to BYC! If you want to figure out the breeds of your chickens, here's a nice guide: https://starmilling.com/poultry-chicken-breeds/ You could also post photos, I'm sure many folks on BYC could ID them :)
@SmiYa0126 has a great idea. When you are looking at animal rescues, they will often call this a barn cat program, although the non-profit in my area calls it their "working cat program". It's a great thing to do since you would be giving a home to a cat that might otherwise be put down.
