I've taken her to the avian vet in the past, but last time was about a year and a half ago. So, before the poopy thing started.
She had an infection once because she had some eggshell that she didn't manage to expulse, but I don't think this is related as this poop thing has been going on for about 1 year.
Do you think that the uropygial gland area looks normal?
I'll make an appointment with the avian vet, which will probably be for next weekend. In the mean time, I would still like to get your opinion.
