Egg prices for consumers fell to 5-month low in May. Here's why.

Consumers are finally getting a break when it comes to egg prices.

Egg prices dropped to $4.55 in May, down 11% from $5.12 in April, according to data from the Bureau of Labor Statistics. The price drop for a dozen Grade A large eggs comes as the effects of a years-long, widespread avian flu outbreak recede and demand for eggs softens slightly, as it usually does this time of year. 

"There are two main drivers behind the drop in prices — abatement in the conversation about bird flu, and some seasonality in uses of eggs. Typically as we move into summer, demand for eggs soften, as people shift to consuming more meat and grilling outdoors," Brett House, an economics professor at Columbia Business School, told CBS MoneyWatch. "People aren't making heavy breakfasts, so we don't see demand for eggs being as strong as it typically is during the winter months."
