Beth McMaster, a wildlife rehabilitator, has been caring for nine birds removed from campus buildings beginning on Saturday. She says one bird was spray-painted pink, another with purple paint, and others with yellow.
Carnegie Mellon officials say in a statement that students are cooperating with the university's efforts "to understand what happened on Saturday, when farm chickens were found in campus buildings." Any disciplinary action will be handled through the school's internal judicial process.
One bird was found in a student center, another in a racquetball court.
