Claudine, coyotes aren't dangerous unless they are rabid, which is very rare. They are great vermin catchers and generally stay away from humans and human habitations. Their habitat is shrinking, so they are closer to people than before, but still avoid us as much as possible. We don't have wolves in central Texas, but some have been sighted in other parts of the state.
Owdboggy, we have foxes, but they are rarely seen. Sandy Creek is near us, and fox have been seen there. We don't have any four-footers in or near our gardens except for stray dogs and feral cats.
Zigs, is that a red fox? We don't have them, but I've seen pictures.
We try to live with wildlife as much as we can, while protecting our chickens and gardens. So far we have fought each other to a draw!
