For both the chickens and the planters, I crush shells a bit and then roast them slowly in the oven until browned. Crush a bit more and sprinkle in coop or potting soil I mix from a local plant nursery and a water treatment plant residue called 'sludge'...shells will keep slugs down in the planters and provides calcium to the chickens among it's other benefits.
