Indy, I have been a Egger for over 40 years. I now live in Texas but when I lived in Denver I was interviewd on TV about my art with eggs.
Willie Nelson's ex-wife has one of my ostrich eggs.
I work with ostrich, emu, rhea, goose (some as large as 11' around the long way), and smaller eggs.
We will be in Belize in late June. Wish I could bring you a box of eggs to work with.
