Check your bedding. Horse pelleted bedding often has cedar in it to help control odor. Cedar is not recommended for poultry so, if it has cedar in it remove it right away. I always use old towels for bedding with my ducklings. They are absorbent, easy to remove, launder and reuse.Yes I sat in there for close to an hour watching the other three and they were drinking and ate a little bit. The new bedding we put in are horse bedding pellets that swell up and become like sand when they get wet. I haven't seen them trying to eat it at all.
