At about 10:30 this morning (October 24, 2015), in Oklahoma, a crowd of people congregated to watch the State University homecoming parade. Suddenly, a car struck a police motorcycle, then drove straight into the crowd. As a result of this, 3 people were killed and 34 others injured.
For birds that are laying large numbers of eggs, an easy and high calcium supplement is dried egg shell ground to a powder and added to their normal feed. Layer pellets are supplemented with calcium as well. Soft or thin shelled eggs may indicate calcium problems in your birds.
A dry chicken eggshell is about 78-94% calcium carbonate (CaCO3). Calcium carbonate gives shells hardness and strength. Laying chickens need about 4 grams of calcium a day to produce quality eggs (source: Butcher, Concepts of Eggshell Quality).
