When I was little I had a hen named Henny Penny ;-) I have a young Buff Orpington now with a "Scissor Beak". Not broken but the bottom goes out to the right at almost a 90 degree angle. She, too, can't eat regular food nor any treats. I soak her crumbles in water and stir till they are a sort of slurry-Much wetter than mashed potato-Then I stir in a blob of canned dog food. She LOVES this. I also soak raisins in water till they are soft. I give the raisins to the other girls and add the raisin water to Beakie's dish. She seems to be thriving but it breaks my heart when everyone else is scrabbling around for meal worms and raisins and she just watches! I do have to wash and dry her chest occasionally and trim her beak. I'm guessing your HP's beak will grow back soon-They grow like fingernails/claws so find some foods she can eat and wait it out. I'm going to offer Beakie some yogurt! Thanks for that idea.
