Yes, they just love hard-boiled eggs. I just toss them in and they attack them!
It seems like they prefer the yolk to the white, but they eat it all eventually.
Here's a really weird one. My Chicken Guru (a gentleman with over forty years
of experience raising and breeding chickens) told me that his mentor used to
feed his chickens canned dog food. So I bought a few cans of different kinds and
conducted a little taste test this weekend. So far, the all-natural stew variety is
leading the pack. The chunky meat bites in gravy from a major brand did not
fare as well.
