@FrankHomestead can you post some photos of how they are housed in your barn?
What are you feeding your chicks?
I agree, it could be frostbite, but the photo below reminds me of Pododermatitis as well.
Do the best you can to remove all that poop/gunk that is in the nooks and crannies of both feet.
A daily soaking in Chlorhexidine would be ideal, but you can use epsom salts. A triple antibiotic ointment or Vetericyn would be better than vaseline.
Chicks can be rambunctious for sure, but spilled water and wet bedding can cause problems, so do your best to stay on top of that.
If you have vet care, that is always best. If the legs/feet do not start to heal within a few days, then you may need to seek further care and treat with antibiotics.
