I moved to a location in Florida where there are deer, two and a half years ago. Since then I’ve been giving them whole corn from a local feed store. The squirrels come and indulge as well. Just recently I notice some of the squirrels have missing fur. I was wondering if there could be something in the corn that could be causing it. Saw on some other post that it could be mites and I’m worried I could be bringing something like that in with the corn.
