Calcium

[Chelly]

Would this be worth a try to add to chicken feed?

Whenever you use eggs, save shells. Wash shells out right after using the eggs and save them up for about a week or so until you have a "batch" worth processing. Bake shells at 350°F for about 8-10 minutes to remove the mineral oil coating and make them brittle enough to grind. Grind to a fine powder in a food processor, blender or coffee grinder (I use a coffee grinder). Make sure there are no sharp, gritty pieces.

1 tsp. of powder supplies about 1800mg - 2000mg of calcium.

Personally I would have it available free choice. Chickens are good at determining how much calcium they need.

Wouldn't this be better than buying a calcium suppliment, like oyster shell and the like?
I guess you could crush it up till its like a gritty texture and let the chickens pik/eat as needed.

(perhaps it could FUNCTION as grit?)

calcium (oyster shell) cannot replace grit.
