Righto - the parents may hunt together to take prey back to their kits. Worse yet, they may use captured prey to teach the vixen how to hunt themselves.
YES it is quite unusal for them to be out in the daylight, but not so much during baby-rearing season. The parents work together. Foxhunters often run a pair because they both lead the hounds away from the vixen.
Foxes are not so bold in our country (foxhunting territory), but perhaps they are not so hungry. If foxes acted like that where I am, rabies would be suspected.
We also have foxhunters in our area that feed the foxes to keep them in hunting territory and away from farms, but really, there is an abundance of natural fox food in our area.
Oh - and we are in foxhunting season in Virginia, so this is the active time for our foxes - big reds imported from England in the 1930s that are not native to America.
