i don't know if I am posting in the right place. I have a chicken who is blind. She makes it around ok but I have to feed her separate from my flock or she doesn't get enough feed. I free range my chickens but feed them morning and night to keep them trained to see me as their feeder. Her beak is getting more square and starting to crack. She doesn't rub her beak to sharpen it like the other chickens. I am looking for help in how to file her beak or trim it in a natural curved shape like my other chickens. Thanks for your help.
