Organic is better
Organic eggs are healthier since organically raised chicken are not given growth hormones or antibiotics. To qualify as organic, chickens must have access to the outdoors including pastures where they can ruminant. However, the organic standards are in direct proportion to the size of the farm. The larger the farm the more crowding there will be along with practices such as debeaking. The secret is to find a small local source, usually at the farmer's market.
