One of my roughly 17 month old Buff Orpington hens was sitting on 6 eggs. We left her undisturbed (i.e., we did not pick her up every day), in her own coop with easy access to food and water. We saw a peep this morning and checked for others. The other five eggs have completely disappeared - no peeps, no remnant egg shells! What happened? The chickens are guarded by Anatolian Shepherds and I have not seen any snakes. I am with or near the chickens several times a day. I have never seen a rat here.
