We just changed to wood pellets for bedding and I'm loving it. We have a tray (just a rectangular lid from a plastic shoe box) under the water container (3lb sour cream tub with a section of the cover cut out) to catch most of the spillage but anything else just runs into the wood pellets and it soaks it up and turns it to sawdust. I've placed hay over 1/3 of the brooder, on top of the pellets, so they have a place to lay down in comfort. So far all I've had to do is change the hay every morning, and wash off the tray twice a day. I remove the hay and the tray, stir the pellets up a bit and replace the hay and tray. Although the smell is not gone (darn) it's greatly reduced. We're on day 4 with the pellets and I haven't had to replace them yet. I've got about 2 inches of pellets in a 50 gallon rubbermaid tote, 2 ducklings per tote.
