I've had far too many chicks and brooders inside all winter. The odor never got to be noticeable. I'm not a crazy, clean it everyday kinda person. I used wood pellets and it kept everything sweet I have 2 Yes just 2...week old ducklings in with my 5 2 week old d'uccles. The smell has been sickening. The ducks are going into their own brooder tonight, but holy stench that's bad! any pointers? Yes, I'll clean it more often, that's a given.
