Administrative Rules of Montana
Department 32 - LIVESTOCK
Chapter 32.12 - EGGS
Subchapter 32.12.2 - Montana Standards For Quality Of Individual Shell Eggs
Rule 32.12.209 - C QUALITY

The shell must be unbroken, may be abnormal and may have slightly stained areas. Moderately stained areas are permitted if they do not cover more than 1/4 of the shell surface. Eggs having shells with prominent stains or adhering dirt are not permitted. The air cell may be over 3/8 inch in depth and may be free or bubbly. The white may be weak and watery so that the yolk outline is plainly visible when the egg is twirled before the candling light. The yolk may appear dark, enlarged, and flattened, and may show visible germ development but no blood due to such development. It may show other serious defects that do not render the egg inedible. Small blood clots or spots (aggregating not more than 1/8 inch in diameter) may be present.
