If you are wondering if you have an allergy, you probably have at least a sensitivity.
I think the feed the chickens get are causing more of us to react to the meat and eggs. My body won't even swallow chicken. The sensors in the throat won't allow even organic chicken to go down. The eggs cause an upset stomach. It started with milder symptoms. I used to be able to eat free range organic with no problem. Glyphosate in feed, and some of the cheapest unhealthy ingredients the companies put in feed are the big problems with most meat and layer IMHO.
Normally, small farm raised free range eggs that are not provided commercial mix are extremely healthy complete protein sources.
My doctor recommends half a dozen or more a day. I did that and felt fine until I developed that allergy. If it was me, I'd go off eggs for a couple months and reintroduce only a few free range organic that aren't fed soy or GMO corn.
