Hi guys I'm new to the forum and am a proud owner of a female umbrella cockatoo. I wanted to ask if anyone has experienced their cockatoos pushing their top beak forward with their tongue up. She hasn't been eating well either or drinking much. She's also lethargic, but her poop looks fine. I've taken her to the vets but was reffered to an avian vet which I've been booked in for. I've attached a picture below, if anyone could help me I'd be really grateful thank you.
