I have a flock of 25 laying hens and would like to mix my own feed. I have all of the ingredients below available. Does anyone have any suggestions on what rations to use. Here is what I was thinking. (I want to use as much flaxseed as possible but I've seen that more than 10% is not a good idea.) CORN 41% BEAN MEAL 30% OATS 10% WHOLE FLAXSEED 10% LIMESTONE 8.5% SALT 0.5% Also what kind of vitamin pack would I need to add. I've seen Fertrell's Nutri-Balancer on alot of sites but not much about any other brands or options?
