Eggs are a useful source of protein, iodine and 
essential vitamins and are almost indispensable to the cook, But I Use them to paint with. Hens’ eggs are the type of egg most frequently used. Duck eggs, gull eggs and quail eggs are less frequently used hard to find and too greasy to work with. I can’t use a Quail egg because they are so cute. Goose eggs and ostrich eggs are considerably bigger and unless I learn to paint with an enormous brush I believe I could never use the entire yolk.
Hi Mary Jane,
This is an interesting question. I have used goose eggs for large projects. I find the yolks need 1/4 as much again of white vinegar than used on chicken eggs to thin and preserve their working time. Free range chickens seem to seem to be the best egg yolks for icons. They retain their consistancy longer and become transparent sooner.
I prefer duck eggs if I can get them. They are usually available in Hong Kong Market here in Houston. It really makes a lovely tempera when mixed with a dry white wine.
