So, yesterday two of my ducks disappeared from my coop. The majority of the run is covered by bird netting and the other is covered by a large tree. If a bird got in there and took them I don't know how unless they went straight up through the tree. The floor of the run was muddy but had no tracks in it. We have been searching the neighborhood and can't find them. There was no feathers to show a fight with a predator. Does any one have any idea of what could have happened. Thanks for any help!
