I had always used the regular Purina Layena and when I saw the new omega 3 I recently bought a bag. I have six chickens and they all seem to eat it the same as the other type. No difference. I used to give them a bit of flax seed for omega 3 and I do not when they are eating the new food. Probably will not buy it again even though I am very satisfied with it. The only reason is that when this bag is done I will continue adding the flax seed so will not need it. It is a bit more money because it is only 40 pounds.
