found reason for egg 'allergy'
I had been feeding my geese rabbit feed and supplementing it to my chickens just to add more "green stuff" to their diets throughout the winter. The layer mash contains a synthetic vitamin K: menadione sodium busulfite complex. the rabbit feed contains that and another: menadione dimethylpyrimidinol bisulfite. Now that my birds are free ranging again, they're not eating the rabbit feed anymore, and the eggs are no longer causing a reaction in me. I did some research and found that these substances are also in commercial pet foods and are causing allergic reactions in pets and there is effort to get them removed. I've taken the feed away.
