So either of a feral population, or, more likely, rabbits that escaped, got released or dumped. With the quite short ears it looks more like some mix of pet breed than a lifestock breed.
I think the farm across street from me is getting in to rabbits. One of the 2 died one the road between us. I can see white rabbits in their field in the evenings. We don't really get a long with them or my dad feeds their dog every day. It comes over to be fed. They own many farms I bet. I felt really bad when the bunny was dead. I have had lot's of cats and dogs.
