I got these from my ex yesterday. They live in Marin County north of San Francisco. She said they've had as many of sixteen of them in the yard at one time and she's about ready to start eliminating them because they rip up her flower beds.
We have lots of Thunder Chickens. I can see over 100 in my neighbor's field in the winter. Some come in my garden but it seems that they go the the branch on my neighbors property in the winter. They must come from all over the place. If we have snow the field next to the branch will have bare ground for hundreds of yards where they dig in the snow. I mean even heavy snow. When I was a kid we had no turkeys and no beavers but now we are over run with both. My grandfather was a trapper and taught me to trap. That is how he made a living in the Winter and he never saw a beaver. The last year I trapped I caught over 60 beavers.
