Well, I don't know if I made it right but we'll give it a try. This is my spring, for my home. It's a good spot the fox. They go under the cattle fence below the spring, you may see in pic. In the pic you see the overflow into the tub for cattle we had years ago. The water never freeze up that close to the tub. I made the water hole two months ago so fox would get use to it. It about 36" to 40" round, 3" deep. Stone with moss on in middle with lure. The grass sod is on the trap pan with a 5' chain and two point drag. May be overkill but the trap is a Sleepy Creek #4 O/S set with 2 lbs.
Let me know your opinion what I could have done different or better, other than waste my time. LOL
The set was out of Stanely Hawbakers, Trapping North American Furbearers.
