Granted it's been over 10 years since I've had diamonds, but my last pair successfully bred. Before that, I had a single diamond that was mostly free range indoors and interacted with us daily (liked to sit on our heads, "wrestle" with our hand when we sat on the floor, etc.)
These two have become more and more sedentary (and quiet). They sit on one perch snuggled together. They don't seem to settle on any of the other perches and seem to only go down to the cage floor to eat and drink. I can't figure out why they aren't active.
Before they would busily load their nest with timothy hay and sisal when I put some in their cage. Now they ignore it completely. They just sit. They don't appear ill. But I don't understand.
