Try Applegate chicken products, in the freezer section.

Commercial poultry is also fed shellfish in some instances.

Fortunately, we have the room to bypass allergies by raising our own chickens & turkeys on a soy free diet. It's been a learning curve, but I am so grateful we have been able to do this. Commercial poultry is usually injected with a soy product, as well as being raised on soy feed. I couldn't eat commercial turkey for several years because of the soy allergy. It is wonderful to have eggs & poultry meat that is soy free. The kicker is I am allergic to feathers. Fortunately, I have a wonderful spouse who fully supports my struggle.

Unless it is certified organic, all poultry is loaded with antibiotics.

I can only eat free range chicken or turkey
