What bothers me is my cage of four female budgies, two of which mate with each other and lay eggs (!!!), toss all their food on the cage floor by kicking with their feet. Chop, seed, everything, and won't eat off the floor. I like to collect food waste out of their bowls and feed it to the outdoor birds but I can't do it when it's mixed with poop on cage paper. The boy's cage budgies never do this, nor do my other budgies. As it is, there's at last a full cup of wasted food a day except for those sloppy girls so there's a lot of wasted food. But, I love my wasteful kids anyway and it's not that expensive. I estimate that I spend at least $75 a month on food for my 19 budgies, including chop, other fresh veggies, seed (I mix my own from white and red millet, oats, and sometimes other goodies like hemp seed, chia seed, and chopped sunflower meats), and occasionally spray millet, but it's horribly messy and allergenic.
