It is essential for me that my chickens have grass. They are happier and the egg yolks are darker/ since free range chickens have more nurtrious eggs with less cholesteral, grass and other green plants have a part in that. Due to predators my chickens have very limited free ranging. I feed them kitchen and garden scraps, weeds from the garden and flower beds etc, green material but a variety. They seem to enjoy this and if there is something they don't want to eat, they just turn it into wonderful compost.
Some folks plant raised beds covered with hardware cloth or other small wire and plant greens or grass. Supposedly the chickens don't obliterate the whole crop because they can only eat what they can reach thru the wire.
However Smittenroade is correct. Some commercially raised chickens never see grass.
really?? I was of the impressin its very good for them and cheap as greens cost a fortune these days. course grass clippings are good to over the fence LOL,
I was just answering the question that it's not important. Makes them more healthy, but I doubt you would really tell the difference...It's really greens including weeds and stuff, not just grass. You could substitute lettuce, broccoli...Ya know, leafy green veggies probably more nutritional quality in those.
