Runner Duck acting strange

[rfb1928]

I have a white female runner duck who is about 3 years old. Normally well in herself. She is eating and drinking normally. Has lost no weight. But is unsteady on her feet, staying in her bedding/nest area lot, not really going to her pond much to swim. Her male partner duck is completely fine. Any advice or help would be great. Thank you. Highlighted words are symptoms.

Does she lay? if so when was the last time? any unusual pushing or pulsing from her vent? Do you have any Calcium gluconate to give her in case it's a stuck egg?

She hasnt laid in nearly a year. Her vent is clean and normal. I have even felt for an egg and given her a warm bath too.

Sounds like we can rule out egg binding maybe. Saying that because my older muscovy will go for a year without laying and then low and behold I'll find a muscovy egg. It wouldn't hurt to give her some calcium Calcium gluconate this helps move an egg on down and out. 1 ml over a small amount of treat. If she isn't eating then it can be given by mouth.
The only other thing I can think of is a niacin deficiency it happens in adult ducks too but we see it more in ducklings. Liquid B complex is what we give for this.

How does her poop look?

Okay thank you. She has never been one for laying eggs. Ive maybe had 8 eggs in the 3 years of her life. Her poop is normal to what it always has looked like for her. Bit runny and solid. Green and or white / brownish.

She could have some kind of infection. if you decide to try either or both Cal glu and liquid BComplex give it at least a week . If you don’t notice any change then I’d go for an antibiotic. Baytril is the one most used. Might be a good idea to order an antibiotic so you have it on hand
