Right? These things are as big as my roosters. As I said in my original reply, the guineas were fighting with them, but the ravens weren't backing down. If I hadn't gone out there, there's a good chance the ravens would have teamed up and killed the adult guineas. It's not one bird, it's a pair and all their offspring.
And I just caught that this poster has now said that if the ravens could get my duckling, so could a rat, cat, or a dog. Um, no. They were in an elevated brooder the bottom of which is three feet off the ground and the latch is even higher up on the top. The ravens literally flew up there and knocked the latch loose. No way I could have foreseen that and no way another predator could have done it. I will of course be switching to a different type of latch now.
And it also seems they did not read my reply about all the trouble these birds have caused me over a course of an entire year that I did nothing about because they are convinced I want to poison them over the loss of one duckling and two keets, which is not the case at all.
But! I said I'd stop talking about it and I will. I can't let myself get all worked up, lol. I want to thank everyone for the support, though. And now we should probably let this subject drop and get back to talking ducks
