There was an episode of some TV show where someone thought they were allergic to poultry but it was actually an allergy to the antibiotics in the poultry. Maybe the parts of turkey or the processing methods used for hot dogs contain less antibiotic residue?
He may well be allergic to something in their feathers. While I am not a huge fan of hot dogs and what goes into them I suspect that even the worst manufacturers draw the line at letting feathers into the vat.
