Egg food is so simple to make. Here's the recipe.

2 Eggs hard boiled, cooled and fully cooked until yolk is hard all the way through. 12 minutes boiling works for me to get my eggs to this point.
1 Potato Masher
1/2+(to consistency) cup of crushed cereal O's (does not have to be the name brand of O's), crushed until powdered
1 Slice of 12 grain bread dried stiff or toasted, crushed into bread crumbs.

Place the crumbs in a bowl. Place the eggs in a bowl and mash with a potato masher until they are teensy. Mash the shell as well, and make those pieces as small as possible and include them in the egg mash. Usually 1/16 inch is sufficient for all sizes of bird to eat. Place bread crumbs in first. Mix thoroughly with the egg and then add the cereal O's to it. Mix this for about 2 minutes until very well mixed. If Egg Food is not dry and still feels mushy or wet, add a bit more of the crumbs or cereal until it becomes spongy. Put this on a dish in the bottom of the bird cages or aviary and the birds just eat it up. You'll be amazed at how fast it disappears.
