Sure. With me it is actually algae build up not poop. Poop does not last long with the climate I have made in my greenhouse. At the new location the greenhouse is under the cover of trees meaning the greenhouse and the greenhouse plants do not receive as much direct sun light compared to when they were out on the ranch location. However whenever I have got extra time when I am tending to the greenhouse water blasting the greenhouse walls and chameleons enclosure is a regular duty.Make sure to clean those 'poop out windows'. Never seen anyone do fecal checks like that before.
Greenhouses should be a prerequisite for keeping chameleons. In my opinion, the only true and humane way. In all fairness, I myself am forced to use cages due to living in a townhouse. Makes me feel guilty sometimes. I do take advantage of my skylights and had french doors installed in the back room. I can swing them out to let in sun when the weather permits. I converted my shed once for herps, but am afraid of theft. It's a no win situation. Looks GREAT Jeremy. A true responsible chameleon keeper.
