Don't really know what category to put this under. Yesterday I found an egg in the backyard. The chickens have NO access to the yard. The dogs are out there a lot and there is a 5 foot fence with an electric wire along the bottom (on the dog side) 6 inches up and 6 inches in to prevent digging. The dogs have NO access to anyplace the chickens can go. Soooo.....how did the egg get to the back yard? It was a small egg, pullet size, and definitely a chicken egg. I live in a rural area. Have never seen possums, coon, foxes, or skunks around, except as roadkill. (Smelled them occasionally.) These animals would not have been able to come in the yard anyway, due to the three dogs being there and several fences. Have seen a few hawks (small ones). If a hen laid an egg out in the chicken yard instead of in a nest box, as they do occasionally, could a hawk have picked it up and carried it? And why leave it and not eat it? And wouldn't it break if it dropped it? I do have snakes, but they are not active in this cold. No sign of rats or anything like that around the coops. The egg was undamaged, no tooth marks on it, no cracks. It was frozen solid and rotten. Stunk like a son-of-a-gun when I cracked it. I don't know how long it had been there, but I think I would have noticed it fairly soon. It was right along the path where I go to the workshop to get the chicken feed. Well, I'm stumped. Any ideas, anyone?
