Apologies if this is the wrong sub for this, just want to make sure it's nothing contagious since our neighbor feeds them (hoping to report him soon) and I don't want it spreading while they're tightly packed eating the food.

they were not close and the fog was starting to develop (flashlight does not help much in this situation) they would pause, watch us and then start up again

Big boy is resting up a bit before getting back after the neighborhood does.
