I think they are different wolves jager.....the Rice wolves "supposed hybrids, locals think they know who released them" stay pretty close to their homeground, they are mostly being seen in about a 2x4 mile area by what I have heard.
I have heard about the Fruitland wolves but there are also Springdale and Hunters wolves I have heard about, but I bet they are all the same wolves. Wild wolves are going to cover a lot of ground.
