Any advice would be welcome. I nursed her back to health for about 3 weeks from not being able to walk on both legs to walking fine and then suddenly a week or so later her right leg is weak again and she limps on it but not all the time it seems to be on and off. She also pants while the the other ducks are not. I know it's been super hot lately and she has been panting even before. I gave her Tylan 50 every other day for 5 days thinking she had an respiratory infection along with nutritional yeast and she did better over the next few weeks. She is active and running around getting into the pool and seems normal except for the heavy panting and limp. She had been laying eggs too. I keep wondering if it's her lungs. She has one blind eye and so she has always walked a little bit on the wobbly side but this is for sure a limp. She has no bumbles and her legs look good. I'm not sure what to do for her at this point. We've had so much rain and it's always wet but they have a large area that is covered away from the rain if they need shelter but you know how ducks are. I am worried about her.
