ive looked at all different feed recipes and most contain either bone meal, fish meal or soybean meal. the more complicated ones have both bone meal and fish meal and some contain all three meals. so is it worth it to buy multiple types of these meals or is just one enough if the protein is right. and what is the best type? i add alfalfa meal to the feed but if my birds free range all day is it even worth buying more when i finish this bag? right now i add 1 lb. of kelp to every 50 pounds of their feed but i recently discovered poultry nurti balancer which contains kelp and other supplements http://www.fertrell.com/poutrynurtibalancer.htm is this stuff better then using kelp in the feed mix?
