Another source of calcium for egg shell formation is the complex of medullary bones, which store and release calcium during the night when the hens normally have no feed intake. Relying too much on the medullary bones, however, leads to a loss of phosphorus and bone strength.

Observations of feed intake behavior suggest that the hens consume roughly 1/3 of the daily amount during the first half of the day and 2/3 during the second half of the day. Feed composition during the afternoon is important to meet the higher demand for calcium during the night when most of the egg shell formation takes place. Many layer farms are therefore using a top dressing of 12% coarse limestone .

Understanding Limestone Quality and Calcium digestibility in Poultry Feed Limestone included in poultry feed is the single largest contributor of dietary Calcium required by our birds for good bone and eggshell formation. In spite of its importance as a calcium source, little is known about the digestibility of the calcium from limestone, and how to best characterize differences in limestone quality.
