I also have both sizes of the @Brinsea EcoGlow and can't say enough about them! I've raised 4 batches of chicks with them and they are a GODSEND! No worries about fires, lights being on too long, raising or lowering heat lamps, buying extra bulbs or bulbs of different wattages, or using a lot of electricity! Plus, they are easy to clean. The chicks learn to regulate themselves, whether they go completely under it, lay toward the edge of it, or race around the remaining part of the brooder! The height can be adjusted easily and you can even place a piece of wood under one leg so that one side is higher than the other! I actually think that the radiant heat is better for the chicks instead of baking them under a heat lamp. Once the chicks are hopping on it, you can clean it off with a plastic ice scraper and then wipe it down with a lysol wipe. You won't be sorry if you buy an EcoGlow! They are fantastic! Remember to register yours right away and get an extra 2 year warranty. Also, Brinsea offers 10% off coupons if you "like" them on FB. Best of luck with your little fuzzy butts!
