It was such a shock to come out this morning to do my rounds and discover that one entire clutch was gone! Was unguarded, not being sat on yet. I have all my ducks as far as I know (one is likely sitting next door). We have all kinds of predators....have found occasionally the odd egg yolk here and there out in the middle of the yard..maybe Ravens? I hear they are very brave, will even go inside a hut.. Anybody else have this happen?
