I know this is an old thread but maybe future owners like myself of the Eco glo could put press and seal wrap on the top to keep it clean and change that out. Does the unit get hot on top that would prevent that?I am learning with the ecoGlow myself. Mine are almost 3 weeks and seemed to have a hard time getting under and one chick in particular seemed to be pushed out all the time. I know it says "most chicks" will prefer the lowest setting all the time, but I did raise mine this week and the reason I did was I plan on keeping it out in the coop for an extended period. It's cold here and a local chicken expert said just keep it out in the coop for a longer period of time as a place for them to go warm up as desired. Trying to raise it with a screw driver was way too frustrating, so I have it up on a 2"x 4" my husband ripped in half. They seem to like it and now everyone can huddle without anyone being pushed out. I have 5 chicks.
They only use it at night, and only very rarely during the day. The poop on top is a real pain /img/smilies/sickbyc.gif
