Pacific Pearl Oyster Shell – Nature’s Best Calcium:

Oyster Shell Calcium For Poultry

FOR LAYING POULTRY:  Our crushed oyster shells are crafted and sized to provide essential calcium for all laying poultry, including chickens, ducks, and quails. Whether you’re tending to backyard flocks or managing commercial farms, our product is the perfect addition to your chicken feed.

OYSTER SHELL CALCIUM:  Our oyster shells represent the industry’s purest and highest form of calcium carbonate, ensuring that your poultry receives a high-quality, easily digestible source of calcium.

STRONGER EGGSHELLS:  Crushed oyster shells are an excellent source of calcium for chickens, providing the necessary nutrients for proper eggshell formation. This results in high-quality eggs and a healthier flock overall.

HEAT-TREATED FOR PURITY:  Our oyster shells undergo heat treatment to ensure maximum purity and cleanliness. This process prevents the occurrence of harmful contaminants, bacteria, and pathogens, making it safe for your poultry to consume.

MADE IN THE USA:  Our pure oyster shells are proudly harvested and processed in the USA, with no added ingredients. By choosing our crushed oyster shells for laying poultry, you’re ensuring your birds receive a high-quality, domestically made product that you can trust.

Lay Shell Blend

Lay Shell Blend features a variation of shell sizes from 1/8 inch to 3/8 inch, blended together for a uniform shell mix. Promotes optimum dietary calcium utilization for enhancing eggshell quality in layers. Available in 50 lb. bags.

Grow Shell Blend

Grow Shell Blend is designed primarily as a start/grow feed ingredient for young chicks through age 20 weeks. Not recommended for laying hens because the size does not maintain adequate retention time in the gizzard. Available in 50 lb. bags.

Pigeon / Cage Blend

Pigeon / Cage Blend consists of a very fine grind designed primarily for the pet bird feed formulations. It is also excellent for larger sized birds such as Emus and Ostriches. Available in 50 lb. bags.

Flour / AG Lime

Flour / Ag Lime is finely ground oyster shell that has a smooth velvety feel. Its texture and high quality make it highly desirable in numerous commercial and agricultural applications, and well as a feed additive. Available in 50 lb. bags, bulk bags, and in bulk.







Five outstanding reasons why oyster shell calcium gives superior AG liming results:
  1. Oyster shell is produced by a living organism Calcium formed in this non-crystalline state is more easily dissolved and utilized by the soil and plants
  2. Particle shape and texture
    Oyster shell calcium is formed in thin, delicate layers that readily break down into flake-shaped particles
    The porosity and irregular shape of the shells exposes an immense surface area that reacts with acids in the soil
    The oyster shell particles anchor themselves in the soil and resist leaching
  3. High calcium carbonate analysis
    Guaranteed minimum calcium carbonate 96%
    Guaranteed minimum calcium 36% (typically 38% – 39%)
    Moisture content less than 1% (average .2%)
  4. Sized specifically to cause a timed release of calcium
    1/3 fine particles to produce a rapid pH change (-325 – 200 mesh)
    1/3 medium particles to replace calcium as it is leached out or taken up by the plant or turf during the growing season (100 to 60 mesh)
    1/3 coarse particles to provide a long-term source of calcium (40 to 20 mesh)
    Approximately 55 lbs. per Cu. Ft.
  5. Oyster shell supplies additional plant growth requirements
