These are the first guinea fowl eggs I've seen. I'd never seen guinea fowl until we moved to Tennessee. One wandered into the yard and stayed for a while. I've heard they are great for keeping a yard free of ticks. A volunteer came by today to give me these (and another goose egg) to blow out, dye, and carve. Obviously I don't just like to decorate eggs at Easter.
The eggs are small and I was told they have a tough shell. I haven't done anything with them yet, except wash them. I don't know if all guinea fowl eggs are mottled-looking or not, but I think the dye effect will be interesting.
