Last a good amount of time. Perfect size to fill my gravity feeder ( cat food dispenser) . No smell, no sharp edges that i can see. My girls like it and seems to work well.

Good for chickens and harden up egg shells
Great for the chickens, my egg shells were very thin and after feeding these and few weeks late I noticed the eggs were harder to crack.
