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.
This study shows that egg shell powder is a source of bioavailable calcium. Furthermore, this pilot study indicates that the chicken egg shell powder enriched dairy-based supplement increases BMD of subjects with a low bone mass in the short term and as a consequence delays bone demineralisation for a longer period.
