Foxes confirmed visually. Actually, we had both seen momma vixen in the last couple of weeks, and I've smelled her at various times and locations, but today Gary ran into the house to tell me he'd seen two kits at the burrow entrance under the NW corner of the arena. I grabbed the camera and we tried to sneak back out there, in spite of the sheep and Tess yelling at us and the neighbor dogs barking. Turns out they were barking at the vixen, whom you see in this photo right of center.
For a couple more shots, including one baby, look here.
It was amazing to watch the fox and the Cairn terrier next door almost playing with one another. He would chase her, then she would chase him. She actually barked more than he did, though her bark is not as loud as his. I was surprised when the teen girl came out carrying a halter and lead rope, evidently headed back to their horse pasture, and told the dog to "Leave her alone." This was in reference to the fox, so she is aware of momma and apparently not concerned about the chickens or turkeys. (I suspect the kids don't think any more of the poultry than I do.)
