Hi. One of my budgies who is normally very vocal and happy has suddenly become very quiet and acting out of character. Normally my 2 budgies are not very close and remind me of a bickering pair of teenagers. Now the female one is not really cleaning herself properly, the other one is doing it & he stays by her side the whole time. She seems to be snuggling up to him a lot & sometimes has her head under his wing. They’ve even started sitting on the swing together again (which they haven’t done for well over a year). She’s still eating but something up is very off. I worried that the shock of taking her to the vet may cause her more worry. Any ideas what could be wrong or the best thing to do for her?
