I have a 2 year old call duck that has mysteriously vanished. We know that he disappeared in the evening and there is no sign of any struggle. I couldn't find him, so I wasn't able to lock him up for the night and I just assumed he would be back in the morning. He has been gone for a bit less than a day and his mate is sitting on eggs. She was very distressed when she came out to eat and couldn't find him. I have checked all over the yard and in neighboring ponds, but he is nowhere to be found. He sometimes goes under our deck, but he wasn't there! He has been getting more and more adventurous and flying out of the fenced in yard. Is it possible that he just went out to find a new mate or do you think he was snatched by a predator?
