Smelly droppings

[Tziporiah]

Hello, my Sennie and tag have been experiencing smelly droppings for the last 6 months. . I have had Petey 20 years and have not had this issue before
I took the Senegal to the veterinarian and they did a fecal and a colonial test. She said the fecal test was normal and told me to monitor her if any respiratory system should arise and sent us home
The smelly droppings are still happening for both birds

Are either of your birds currently on antibiotics? If they're not, you could try using apple cider vinegar in their water. It has to be a brand that contains the "mother culture", like Braggs for example which is the one I use. Below is the dosage chart based on species/weight etc ...

I hope this helps!
