Poultry Judging Practice Test

What classification would an egg with a deeply stained shell fall under?

1. Grade A

2. Grade B

3. Grade C

4. Grade D

The correct answer is: Grade C

An egg with a deeply stained shell would fall under the classification of Grade C. This grading classification takes into consideration the overall quality of the egg, which includes the exterior condition of the shell. Grade C eggs are known for having significant defects or imperfections on the shell surface, including stains, which can be a result of various factors such as handling, contamination, or environmental conditions. Eggs in this grade are typically not suitable for sale to the consumer market in their whole form due to these visual defects. They may still have acceptable interior quality for certain uses, but the shell's appearance is a key factor in the classification process. Grade A eggs, on the other hand, have clean and unbroken shells with no defects, while Grade B eggs may have minor stains or roughness but are still considered better than Grade C. Grade D is not typically used for market eggs, as it indicates a poorly maintained egg that is likely unfit for sale. Therefore, the presence of a deeply stained shell directly aligns with the characteristics that define Grade C eggs.
