you can use earthworms but put them in some kitchen paper towel and pop them into the fridge over night. That way you'll get the cr*p out of them.
Beefheart mixes are easy to make. All the hardware you need is a beef grinder and a sharp knife. I use a filleting knife. Take two beefhearts and cut the fat, arteries and sinews from it. If you can get turkey heart use this instead. 6-8 cloves to garlic, 2lbs of fish ( I get a mixture of cod, salmon, etc.) 1lb of spinach, 2 eggs yolks. You can add some vitamins if you like. I also add some cod liver oil (2-3 table spoons, just make sure it's not flavoured). Everyhting takes two trip through the meet grinder set on fine. Job done.
