Cracked feet Barred Rock hen and rooster, EE look fine!

[Almostmagic]

Why would the feet on my Barred Rocks be cracking and bleeding a very little(only hen), and my EE hens(2) legs look GREAT? All kept in same coop, new at chickens this year, raised these myself, no chickens ever here before. Could it be mites or chapping or something? It got SUPER cold here in like 1 day. Can you get mites if no chickens ever in coop before? Thanks I would post pics but not sure I can I will check my camera, not too good at that stuff sorry....

Sounds like it could be from the cold especially if the temperature dropped gradually.

Could be frost bite. Look for articles on frost bite in the search bar.
