Calcium Supplements for Chickens. Crushed oyster shells are an excellent source of calcium, and are the most common way flock owners supplement calcium in their flock. Some people also clean and crush their used egg shells and feed them back to their hens. This works perfectly well, even though it may be a bit time-consuming.

The use of lime in poultry production can have several effects. Lime application to litter increases the pH of the litter. When litter reaches pH 12, cell membranes of pathogens living in the litter are destroyed. Lime reduces the nitrogen content of litter by increasing ammonia volatilization. For this reason, it is important to refrain from ...

Sodium and potassium are electrolytes important for metabolic, muscle, and nerve functions. Magnesium also assists with metabolic and muscle functions. Grains are low in minerals, so mineral supplements are added to commercial poultry feeds. Limestone or oyster shell are common sources of calcium.

Limestone is a very common ingredient in poultry feed. It contains high concentrations of calcium, making it an excellent choice for birds that require calcium supplementation. It is not as easily absorbed as an oyster shell and can be less expensive, but the calcium content is still relatively high. The insoluble form of limestone ...

the Dutch feed tables (CVB, 2016) specify that the total Ca content of limestone is 38%, whereas in a survey of 192 fine limestone samples, Plumstead et al. (2020) reported that the analysed Ca content ranged from 30.4 to 40.0%. More recent literature has indicated that the Ca content of limestone can be as high as 42% (Anwar et al., 2016; David
