I'll hop in. Some of these I've already posted in the polymer clay thread, but since that's buried and I've made some new ones...
Formed around a chicken egg, cooked the clay, then dissolved the egg in vinegar.
Formed around an ostrich egg, cooked it, then broke it apart and glued it back together again minus the egg.
Extruded the clay, formed it around the chicken egg. Random patterns, but I think that one looks like a condor.
Swans on a goose egg.
Included some glass additions, it's actually a bit lighter/brighter than the photo implies, but I'm a horrible photographer.
