Yesterday, I was free ranging my birds and my dog attacked my Speckled Sussex Claire. Usually the dogs herd the goats and never cares about the chickens. At the time I was cleaning the coop and I heard Claire clucking. there was no blood only feathers and you can't even tell she was attacked. Claire is in shock and she's not eating or drinking, only standing in the corner sleeping. My frizzle hen was in shock once but she was ok in a couple of hours. should I be concerned about Claire or will she start eating and drinking soon?
