I got a huge bag of alfalfa pellets for horses two weeks ago. I soak around 3 cups of the pellets in a tiny bit of water overnight. They expand and smell kind of strange. It looks very fine once expanded. I then mix it with my crumble every second day. I don't put enough water for it to feel wet when I fluff it up in the morning. It's very dry. The chickens will not eat it like that (at least mine won't). They do eat it mixed with their feed, though they hated it at first. It has turned my yolks more deep orange than I have ever had before! Even when there was tons of grass for them to eat! The alfalfa is much better for yolk colour (IMO).
