Eggs are lifted from trays and transferred inside a machine that provides a new technique to enable hatcheries to peek into millions of fertilized eggs and spot male embryos, then grind them up for other uses before they mature into chicks, in Wilton, Iowa, Dec. 10, 2024. This is an alternative to the longstanding practice of chick culling where male chicks are killed because they have little monetary value since they do not lay eggs. (Courtesy Tony Reidsma via AP)
