New young squirrel in my backyard

[Randy14]

This morning I saw a new very young squirrel, maybe about eleven weeks old, but uncertain of the species. My neighborhood is dominated by fox squirrels. This squirrel has the coloring of a ground squirrel, but the tail looks too bushy. Or maybe a grey squirrel. Don't know how this young one made its way to my yard. It is rare for me to spot a grey in my neighborhood. I have two photos to post on this little guy. Any suggestions on what species this is ? My other conjecture is it may not survive in my neighborhood with most/all squirrels foxes.

Many Thanks......292277292277292278

It looks like a grey squirrel to me. Can the two species (grey and fox) not co-exist? I don't know, we don't have fox squirrels in Florida.
