Effect of the Calcium and Phosphorus Content of the Diet of Chickens on Egg Production and Hatchability
TLDR
The effect of the calcium and phosphorus content of the diet of laying pullets and hens on the production and hatchability of eggs has been studied in this article, showing that a high level of calcium intake of laying chickens has a deleterious effect on the ability of their eggs to hatch.About:

Nutritional Investigations with Turkey Hens: 4. Quantitative Requirement for Calcium
TL;DR: The National Research Council (1960) recommended a level of 2.25% and an experiment was conducted to estimate this requirement and the results are reported here as mentioned in this paper. But no published information is available on the calcium requirement of turkey breeder hens.

TL;DR: Schaible (1941) reviewed the results of research in minerals in poultry nutrition but the complexity of this problem and its great practical importance make it still a subject of further research.

The Calcium Requirement of Breeder Turkeys
TL;DR: These experiments indicated that the best reproductive performance was obtained when the diet contained the highest level of calcium, so long as it was not too low, with the optimum phosphorus level being approximately 0.75 percent.

TL;DR: Very few data are available in the literature on the calcium requirements of laying hens, and those available are controversial.

Observations on the Mineral Metabolism of Pullets
TL;DR: The interpretation of the rule enunciated by Knowles et al. to mean that calcium and phosphorus are normally excreted by the pullet as dicalcium phosphate and calcium carbonate was shown to be untenable in view of the fact that the droppings may obey this rule and yet contain considerable amounts of phosphorus in organic combination.

Mineral Balance Studies on Poultry
TL;DR: In this article, it was shown that the pullets displayed a diminution of the calcium and phosphorus in their droppings over a period of about 2-3 weeks before laying, and a correspondingly increasing retention of these elements.

Studies on the calcium metabolism of laying hens.
TL;DR: That there is a definite rise of serum calcium in mature pullets as they approach their laying period has been repeatedly demonstrated and marked parathyroid development coincident with the growth of the ova in the hen is demonstrated.
