In many animals, stones are related to diet, and this may be a factor in the development of bladder stones in horses.

Bluebirds will start laying eggs in April at the earliest in Michigan, and may be several weeks later in the northern part of the state compared to the southern areas. Bluebirds usually lay one pale blue egg per day, up to as many as 7 or even 8. The most common numbers are 4 to 6. A small percentage of bluebird eggs are white, but this doesn't seem to affect hatching rates. The female will start sitting on the eggs once ALL the eggs are laid.
