Chickens love their families, have complex social bonds, and value their own lives, but those used in museum exhibits are denied everything that’s natural and important to them. Even before they’re hatched, chicks need their mothers, who carefully rotate the eggs up to 30 times a day to maintain the proper temperature, moisture, and positioning. Chicks grown in an incubator can become sick and deformed as they develop, because their needs aren’t met during incubation. For example, their organs can stick to the sides of the shell if the eggs aren’t rotated properly. Please urge Chicago’s Museum of Science and Industry to end its cruel chick-hatching exhibit and stop using cow eyes—which come from slaughterhouses—for dissection.
