That solved my problem. A funnel is a great idea. I have been using a plastic tray that goes under a flower pot to cover the top of the feeder. They like to sit up there and then poop and it always lands in the tray of the feeder.
Thanks for the idea. And as far as keeping the little flying buggars in the brooder, I use one of those expandable window screens. I don't have alot of chicks at any given time so I use either a large clear storage tub or a 20 gal aquarium. I put the screen on the top of either one. Which ever is being used. The screen does't cover the large tub completely but they still can't get out. It expands to cover lengh wise but not width.
