Ny broody cochin is setting 11 fresh eggs that I placed under her last Sunday. By Wednesday, one was missing, and I had 10 eggs. Today, when I put some new hay in the nest box, which is on the coop floor, there are 8 eggs. No evidence of shells, yolks, etc. The coop is shut tight at night, and she is in her nest box almost all of the time. She has food and water within 12 inches of her nest box. The coop is in my garden, no dogs, snakes, etc. around.... I have a regular size garden in a tract house neighborhood. There are 7 other chickens around that are not broody, and do not bother her. Any idea where those 3 eggs disappeared to?
