Growing Fruit Flies for Your Hummingbirds?

Okay this is a little different. I just saw this product at Duncraft is a respected manufacturer of wild bird products.

Hummingbirds drink nectar from flowers and hummingbird feeders but they also eat insects. So Duncraft has devised a way to grow Fruit Flies.  Basically you let the fruit rot inside this new Protein Feeder” and naturally you will get flies – so I guess it could work.

If anyone has tried this please let the staff at SuperShakerNectarMaker(TM) know!
