I noticed last Sunday that my Cayuga was acting off. She seemed to be gagging a bit just pecking around at the grass during the day then she just out of the blue flipped on her back. I picked her up and she seemed all normal - she clearly didnt care to get away from me at all so it was easy to catch her. I left town for the week and told my boys to watch her - they didnt note anything odd. When I got back Friday she wasnt with the flock she was hiding under a tree up against the house all by herself. Again everything looks fine but she seemed off. I gave her a bath in warm water and gave her some Poly vitamins incase of a vitamin deficiency. Tonight I woke out of bed to the chaos in their cage only to go out there to find all the ducks corralled in a corner and she was flipped upside down with feet in air laying on her neck - clearly she was dead I thought. I reached down to pick her up and she perked right up like nothing was wrong. I have her taking a warm bath again. Both times in the bath her poop was clear/white and just a small bit of green (they eat algae in the pond). Any idea what might be wrong with her? The rest of the group is fine no seen issues. I am going to keep her in the tub a few days to make sure she gets vitamins and nutridrench in her water. I have some antibiotics should I give her some just in case? I also will put some ACV in her water? I am going to give her some baby food with a fat syringe just to make sure she has some food in case she isnt eating. Any help would be greatly appreciated! Thanks!
