Not all alfalfa is the same. My birds won't eat the orchard alfalfa which has more of a broad leaf. I do buy nice green small leaf alfalfa (variety unknown) and they go nuts over it and eat all of the little leaves off of the stems. I have used the alfalfa cubes and they did eat it too after awhile. I did soak the cubes in water. They really like the small leaf alfalfa best and when I don 't have enough vegie scraps for them then I put out the alfalfa so they can get some green. I do let them free range when I can be out with them as we have so many predators around (hawks, coyotes, dogs, foxes, racoons, etc). I have lost birds to a possum, bobcat and dogs that run loose in our area, so I don't let them out unless I'm out. Now I have an electric fence as each time the predator dug under the fence.
