Her face is swollen. I see it on Bucky too.Oh I'll have a look at that. What does that mean?
It means they have a disease. The most common culprits are Mycoplasma Gallisepticum and other respiratory infections. It can be very dangerous and is super contagious, causing sneezing, nasal and ocular discharge, and moderate to severe facial swelling, particularly around the eyes and nose.
I can definitely see some swelling, and they look unhealthy. If they were crammed in a dirty space with other birds before purchase I would doubt their health and disease-carrying status.
MG, if that is what is causing the visible swelling I see, is very common and is not curable. Once a bird has it it's a carrier for life, and you have to treat any symptom outbreaks with antibiotics.
