I was wondering as when I don't have time or we're gone, my macaw parrots will have a 2-3" pile of mushy poo below where they perch most of the time. There's only pellets in a bin in one of there cages as he poops water constantly. Never had any of their piles of poop get moldy either. Although, out comes the fruit flies!I am completely wrong. It wasn’t mold. It was a shelless egg one of my pullets laid. I feel like an idiot
