Foot infection?

[BMHarness]

So I posted this in the turkey section but never got any replies. So I guess I'll try it here... I have several narrangansetts that are about six weeks old. Earlier today I noticed one of them picking at the webbing between its toes on one foot. I picked it up and on closer examination saw what looked like a tear or hole right where the webbing meets the foot. It wasn't all the way through the webbing and doesn't look like an injury. It looks more as if it began as a blister and is now an open sore. It did have a yellowish color to it which makes me think of maybe a small infection. There is no swelling however. I did everything I knew to do which was clean the entire foot with a damp rag, then pour peroxide over the entire foot, let it dry, then carefully clean the wound with an alcohol swab. Any idea what it could be? It doesn't seem too bad at this time. Just don't want it to get worse. Their living conditions are very clean and they aren't living in a large amount of feces as the litter is changed daily. Other than the occasional step in poop they are kept clean. Thanks for any help or insight.
