Eggs to blow for a fair display(quail, chicken, duck,etc.)

I have been starting a collection of eggs for a display at the fair in the poultry barn. I am making blown eggs from different birds and mounting them on foam board with labels. It is an educational display for the public to help teach them about the different kinds of eggs that poultry and gamebirds lay.

If you have any eggs already blown or that you could blow out and send me that would be best. They are easier to ship that way. I only need one or two from each species, so that's all you'd be parting with.

I am not intending to hatch or sell the eggs, so if you could sell them for cheap or possibly free it would be best for me. I can pay for shipping.

Some examples of what I am looking for are Guinea fowl, turkey, Quail(any species), pheasant(any species), other breeds of ducks, or anything unusual. I am also looking for other colors of chicken eggs, suck as marans, or EE's.

I currently have eggs from:

Buff duck
Coturnix quail
Goose

Chicken eggs I have are:

green egg
brown egg
white egg
cream egg
