After looking at pricing on new feeders I've decided I can build my own for far less. All in, parts will cost me about $100 and the labor is free. (If you don't count the cost of beer) My question is this, they're going to be 55 gallon food grade drums, is a funnel absolutely necessary, or is it more of a recommendation?
