Higher egg prices drove up inflation, and Walmart grocery revenue

Higher egg prices, an issue U.S. President Donald Trump spoke about often during his election campaign last fall, boosted Walmart grocery revenue, the world's largest retailer said during its earnings briefing on Thursday. Walmart said its grocery revenue rose by mid-single digits in the quarter through January 31, and a Walmart earnings presentation showed that egg-price inflation was baked into that increase. Egg prices have been rising as bird flu, or avian influenza, has hammered egg production in chickens.
