Hiya, this is my sweet budgie called vinnie, she’s quite small and can’t fly very well due to bad wing clipping in her past, my other two budgies are perfectly healthy and play all the time. However vinnie, does not like to bathe, or doesn’t really play, she’ll chew on something a little and then just preen herself a lot, also she can get quite aggressive. Today I woke up with her covered in blood and she had a broken blood feather, after some panicking I was able to sort that out and she’s okay. But I’ve noticed upon closer inspection her beak is suddenly crusty compared to my other budgies and her poop is grey and white? I couldn’t find any information about that online so could someone help please!
