I came home from work this afternoon after being gone for less than three hours, and I found blood splattered in my budgie's cage. My two birds look totally uninjured, have never had problems living together, and I can't find anywhere the blood could have come from.
There's nothing coming from either of their feces, but one of my birds has blood on the bottom of their feet. It doesn't look like they were bleeding, it just looks like she stepped in some.
I'm so confused! I have no idea where it could have come from. There's no change in their behaviour, and they seem fine.
