doing better without eggs

My son has not had any eggs since Wednesday, he still gets eggs when it is in a recipe, like his pancakes. But he has not had any eggs by itself and he is doing better already. He has not had back to back meltdowns and he has handled things like knocking over his drink a little better. So I think that maybe he just can't tolerate eggs, but he can eat chicken so he will still get his meat. I am going to this week slowly start eliminating eggs from recipes and using an egg substitute that is potato based instead and see if he makes any more improvements. I hope he does not build up an intolerence to potatoes. so far his list of foods he can't have are:
wheat
gluten
dairy
casien
chemicals in food
eggs
dyes in food
processed foods
rice
soy
additives in foods

For household cleaners we have switched to non toxic cleaners and detergents, we are using natural toothpaste that does not contain fluride and he takes baths in epsom salts and ivory soap. we only use non toxic crayola brand school supplies and they do not use playdoh, I have to make it homemade with their flour.
