A bobcat showed up in broad daylight today! Just before noon we heard ALL the chickens call ground predator alarm, completely frantic. I ran out on the deck and saw a bobcat run away from their pen back down to the creek. I sent my dog after it, but he hadn't seen it and only reached the coop behind me.... Everyone was safe as they were locked in their pen, but we have started letting them free range a bit more under our dog's (and mine, right now as the dog is still in training) supervision. Now my question is, is a farm collie enough of a deterrent for a bob cat? Would a 50 lb dog be able to handle a small to medium sized bobcat (this one was about the size of a larger main coon cat)? Would the cat just flee, like today, or have you experya bobcat fighting back against a dog to get at her meal?
