What about, what I feel is the MOST important thing of all. Your eggs are CRUELTY FREE. Chickens are not ( hopefully ) suffering in the way the Factory Farm chickens are suffering.
Best advise I have been given, and much research says... approximately 80% meadow hay... 15% fresh mixed greens ( lettuce NOT iceberg ) and 5% quality pellets.
But the Grass or meadow hay is of MOST importance. Not only with the digestive process but also in the grinding of their front teeth...
