I am not familiar eith giving limestone to pets to chew on (I could be wrong here) so I'm going to say that there has been some misunderstanding here. I'd love to clear it u pfor you but I'm going to take the easy way out and just suggest the use of chalk instead of limestone as the calcium buffer. It will work just as well and there should be no confusion.

Buffering agents are used to counter act the acidic effect of peat and toher casing materials. Calcium carbonate is most commonly used and comes in different forms, some more desirable than others.
1. Chalk:
Used extensively in Europe, chalk is soft in texture and holds water well. Chunks of chalk, ranging from one inch thick to dust, improve casing structure and continuously leach into the casing, giving long lasting buffering action.
2. Limestone Flour:
Limestone flour is calcitic limestone mined from rock quarries and ground to a fine powder. It is the buffering agent most widely used by Agaricus growers in the United States. Limestone flour is 97% calcium carbonate with less than 2% magnesium.
3. Limestone Grit:
Produced in a fashion similar to limestone flour, limestone grit is rated according to particle size after being screened through varying meshes. Limestone grit is an excellent structural additive but has low buffering abilities. A number 9 grit is recommended.
4. Dolomitic Limestone:
This limestone is rarely used by Agaricus growers due to its high magnesium content. Some researchers have reported depressed mycelial growth is casings high in magnesium.
5. Marl:
Dredged from dry lake bottum, marl is a soft lime similar to chalk but has the consistency of clay. It is a composite of clay and calcium carbonate with good water holding capacity.
6. Oyster Shell:
Comprised of calcium carbonate, ground oyster sell is similar to limestone grit in its buffering action and its structural contributions to the casing layer. But oyster chell should not be used as the sole buffering agent because of its low solubility in water.

Limestone = High Calcuim Carbonate rock.

Calcuim Carbonate ground to a fine grit is fed to chickens, so they can form egg shells.

Calcium Carbonate also = oyster shells
