Looks like a fox to me. As a soul that has studied many types of mamals it' totally has the marks of a fox. I have seen many a game cam that distorts the image due to the fact that your taking a picture. Regardless, i would set up some small sand traps to determine tracks and take it from there...
I'm thinkin the one in the middle is a brahma and the 2 on the ends are plymouth barred rocks. I also got some brown danish leghorns and black langshans.
