All 6 of Maggie's ducklings were out there this morning. As of this afternoon, there was one. I'm about 95% sure that the culprit was the local raven. It's huge, and "quorks" instead of cawing. Totally not a crow. I saw it go after a duckling last week, but the other birds chased it off. Figured that was the end of it. But, down to one duckling with no trace of the others, and no grass was flattened around the edges of the pen, so nothing climbed the fence and stole them. I don't see a hawk stealing off with 5 freakin ducklings. But I've observed a raven return several times within an hour to the same campsite to steal, each time, a piece of bread from a torn breadbag. So. I'm putting my money on that damn raven. It steals eggs too. $&@! I took the last duckling from Maggie and slipped it in with Goldie. Hopefully Maggie decides to set another clutch.
Hard lesson learned: next batch of ducklings will go into a chicken tractor with momma for 3 weeks or however long til they reach a size that will deter the raven... If said raven is still around come the next hatch. Funny, it is the only raven I've seen in our area. Always alone.
