Oyster shell usage for corn burning stoves:
Oyster Shell is recommended by some corn-burning stove manufacturers as an additive to promote clean burning, especially when the corn fuel is high in starch. Please consult your stove's manual to see if Oyster Shell is recommended for your stove and follow the manufacturer's directions for use precisely.

Burning Oyster Shell is NOT a substitute for daily cleaning of your corn-burning stove. Regular chimney inspections are always recommended. Oyster Shell does not take the place of inspection and professional cleaning of your chimney. For improved safety and home heating efficiency, it is recommended that all chimneys and vented appliances be inspected every year by a certified chimney sweep.

Manna Pro Oyster Shell, 50 lb. is rated 4.3 out of 5 by 31.
Rated 5 out of 5 by from Good value I bought this weeks ago and happy with the result. I just mixed it in the feed, not much so no worry about their kidney problems. For those who never used this before, it is mostly little stone like with some little chunks of shells. Be careful that the bag has an opening on the top, tucked in though. I was amazed that no leaking during delivery or my moving the bag with the opening. Only found the opening when I tried to cut the bag open.

Can I blend this in a whole layer ration and if so what % of ration would you recommend? 100# per ton?

Asked by: Dan8440
When added to a complete layer feed, a common level of inclusion for oyster shell is 5%. So, you would add 50 lbs of oyster shell into 950 lbs of layer feed.

is this crushed small enough for bantams and silkies to consume?

Asked by: hershortness02
Majority of the pieces should be small enough for a bantam to consume, but there could be larger pieces that are harder for them to swallow, and could pose as a choking hazard.
