See Egg Glut Deepens Problems in Farm Economy: Shares in top egg producer Cal-Maine Foods take a hit, as per-dozen prices decline. By Micah Maidenberg and Kirk Maltais of The WSJ. Excerpt:

"Retailers have been quick to pass the drop in egg prices on to customers, eager to make more sales of a consumer staple.
