(NewsNation) — The bird flu outbreak has sent egg prices skyrocketing, but that doesn't mean chicken nuggets are about to get more expensive.

That's because chickens that are raised for meat, known as "broilers," haven't been hit nearly as hard as egg-laying hens, and there's little overlap between the two.

"These are really two different paths and two different industries," said David Anderson, a professor and extension economist at Texas A&M University.

Americans have surely noticed that difference at the grocery store.

Egg prices soared more than 15 percent in January alone and are now up 53 percent from last year, according to the latest Labor Department data. Meanwhile, the price of chicken meat has hardly budged, up less than 1 percent from a year ago.

Here's why egg-laying chickens have been more affected and where prices could go from here.
