Calcium sources beyond cuttlebone?

My canary never touches the cuttlebone I put in the cage. What are other good calcium sources for birds? Especially important since mine just laid an unexpected egg...

I know how stressful this can be. Just know you're not alone and most of us have been through something similar.

Reading this hit home. My canary went through the same phase around the same age. What helped us was removing mirrors from the cage — can cause hormonal or aggressive behavior. Also just accepting that birds are gonna bird, you know?

I've tried a bunch of brands and Goldenfeast is hands down the best value. My Raja devours it.
