This document discusses different types of eggs sold in the market. Standard eggs are the most common and least healthy. Organic eggs are more expensive but healthier since the chickens are raised without antibiotics or hormones. Free-range eggs are healthier than standard but less so than organic, since the chickens have access to outdoor space. Other egg types discussed include bantam eggs from smaller hens, duck eggs which are larger with stronger flavor, goose eggs similar to hen eggs but larger, and quail eggs which are tiny with speckled shells used in fine cuisine.
