This is long but hopefully someone can help. Last tuesday I had a duck wonder into my woods with her flock and not come back, saturday same thing. Thinking its a predator issue I made it so they can no longer freerange my 7 acres during the day. This morning I woke up and my kahki campbell was dead, really was hoping it was a coincidence as she wasnt showing any symptoms of being sick aside from maybe walking a little slower than normal to bed last night. Ive checked on my remaining ducks all day to see if anyone is showing any symptoms at all of illness with nothing. Just went to put them to bed and my runner duck didnt want to get up and walk she was acting like she just couldnt. I pick her up and place her in another part of the yard she take two steps and down again. We carry her up to the house set her down and she attempts to go to the trailer we put them in at night makes it 2 or 3 feet than starts stumbling. While holding her she did leak clear water like liquid from her vent for a minute than proceeded to poop what looked like a normal poop. I put her in a cage with vitamin water, peas and a scoop of duck food on some puppy pads. She again pooped a normal poop but paid no attention to her food or drink. Im completely lost. There no other symptoms, shes quacking and standing up in there but seems to be getting to weak to walk. Any ideas?? I have no vets that see ducks. I have vitamins, vet rx, antibiotics, activated charcoal, electrolytes on hand.
