Due to economic reasons we are having to make some changes to how we feed our flock. Previously we fed only Purina layena omega 3. The cost over the winter was horrible. Nearly put us out of business completely. We were paying $17 a bag @ 10 bags a week plus 5 of scratch at $12 a bag. Needless to say... ouch. We recently found a supplier for whole grains (not certified but it is organic). 40 lb bags of barley or oats or wheat for $10 a bag.... and free delivery if he's already making a delivery our way to a nearby dairy. The birds LOVE the new grains and we are also working to build a fodder growing system to grow the grains over the winters. We will continue to feed a percentage of their diet from pellet but what I don't know is what percentage of each should they get? They are grass/field fed daily. They are decided into two flocks and each flock has about 2 acres of pasture to roam. We rotate pastures about twice a month depending on the time of year. I don't have any caged birds at all. What percentage of each feed should they be getting and how much of each now that the spring grasses are starting to come in?
