I feed a mix of alfalfa pellets, corn, sunflower seeds, rice bran, bird seed, and cat food, all ground together in the blender. My layers won't touch alfalfa pellets unless ground with other yummy stuff. Just don't add oats to the blender if you try it. Oats seem to kill blenders.
The meat chickens will eat alfalfa pellets soaked with seeds and such mixed in. Just the layers who won't touch it.
Do be careful feeding the pellets whole though. They absorb a lot of moisture, usually about 3x their volume in water. Make sure they have plenty of water so the chickens don't get impacted or anything.
