Found one of my broody duck's eggs out in the yard today. The shell was crushed and completely dry--looks consistent with how I'd imagine an egg would look after a snake swallowed it, crushed it, sucked its juices, and threw it back up again. Is that the most likely explanation, or would some other predator treat the egg like that? I'm sure it wasn't just an accident or a kid (I have a yard full of them at the moment), because the shell was dry inside and out and I KNOW it was under the hen this morning (I count them every morning, and they are marked). I love having snakes in the yard for rodent control. But will this one come back and eat all her eggs eventually? Thoughts and tips? Thanks!
