I finally found a feed mill an hour from the house that will custom blend my feed for me. I should save some money this way.... problem is I can't get a quote until I tell them exactly what I want in it...... I need a formula that you have used and like... Example----70% corn, 12% soy, 12% brewers mash, 2 % DE etc. Can anyone help me out? Looking for a 17% grower/layer mix similiar to what I buy at my local Tractor Supply but at a large discount due to volume. The mill could not give me a mix they have used in the past. I guess they have not had a request such as this before?
