I'm looking for a less expensive way to feed my six hens and one rooster. I am currently feeding them 1-50lb. bag of Purina Layena and 1-50lb. bag of cracked corn every 2-3 weeks. I mix the corn and layena 50/50. They also free range on about 1/4 acre. This is becoming more expensive than the eggs are worth. I'd probably spend less if I were to buy the eggs from a grocery store. Now that I think about it, with the amount that I'm compelled to give away, I think that I am spending more... Are there any less-expensive alternatives that won't signifigantly impact egg production and my girls' health?
