I just went out to the coop to give the brats their snacks and found that one of my Bourbon Red hens broke about a 1/4 inch of her beak covering off, exposing the core. There's little to no blood. She doesn't seem to be in any pain, but I'm concerned that she may not want to eat or drink because of it. I've never dealt with a seriously chipped beak like this - most of them have been minor and healed in their own time. How should I go about treating it? EDIT: Would coating it with a layer of petroleum jelly help?
