i live on a 60 acre lake. At the end of my dock I have a gallon coffee can suspended a few feet above the water. I have holes punched around the bottom of the can. When I go fishing, I will put all the fish heads and guts into the can. Within 1-3 days depending on the temperature, maggots build up in the can and begin to crawl out of the holes and fall into the water, making a self sustaining fish feeder. Really keeps the fish hanging out around my dock. I am thinking of doing the same thing for the chickens. Anyone ever heard of any negatives about chickens eating maggots?
