I had a somewhat similar situation with a young raccoon and my chickens, as far as getting personal with the predator. It never dared to come back after I sent the dogs to chase it off.
I only have chickens, and they are locked up at night, so we've never had an owl problem. I always look at them in awe, and it would be sad to see them as villains.
Hope you don't lose anymore.
Thanks, but a pair of foxes have been raiding. I have only a few ducks left. If spring ever comes I'll be refortifying everything.
