I was very lucky to get a tip about beak and nail control indoors, especially in winter when the birds are sometimes confined, as they now are due to Arctic conditions. I was told to use a hunk of granite rock so they can climb on it, scratch and also use it to clean/trim their beaks. I ended up using a patio block on 3 cinder blocks to elevate my waterer (heated dog bowl these days), and they began to use it immediately. Every one of them will hop up on the patio block daily to scrape the nails and they use that scissors-like gesture to trim the beaks and keep them clean. What do you use? I've seen posts recently about overgrown beaks and wondered if the owners didn't know about providing for this indoors. And, will chickens use cuttlebones? I have a few left over from my cockateil days.
