Telling people your animals are raised in a manner that doesn't promote disease is not a gut feeling thing. It is a fact. If you don't think your eggs are safer, you shouldn't be selling them.
But since you mention gut feelings...my gut feels fine after eating my eggs...raw and cooked. How does the gut of those eating contaminated commercially-produced eggs feel? Not so good if the news is correct.
"So far, not one case of food-borne pathogens has been reported among the thousands of pastured poultry producers, many of whom have voluntarily had their birds analyzed.
Routinely, these home-dressed birds, which have not been treated with chlorine to disinfect them, show numbers far below industry comparisons. At Polyface, we even tested our manure and found that it contained no salmonella.
Pastured poultry farms exhibit trademark lush pastures and healthy chickens with deep-colored egg yolks and fat. As with any movement, some practitioners are excellent and others are charlatans. Knowing your product by putting as much attention on food sourcing as you do on planning your next vacation is the way to insure accountability.
The pastured poultry model can provide true ecological enhancement and nutritional superiority for you and your loved ones. Enjoy pastured poultry and eggs at your next opportunity-- it will be memorable."

There ya go! You can test the chicken's manure for salmonella.
And here is more (my google foo is strong today! HIGGGHHHYA!!!)
"Fecal droppings were collected from 31 farms from Wisconsin (nine farms from each production type) and the Southeast (North Carolina, Virginia, and South Carolina; five conventional and 10 pasture poultry farms) in a 1-yr period. The specimens were cultured for Salmonella and tested for resistance to 12 antimicrobials. A univariate analysis was conducted to determine the significant differences in prevalence and resistance. At the farm level, no significant difference in Salmonella prevalence was found on 33% pasture and 47% conventional poultry farms (P= 0.4928). On an individual specimen level, flocks reared conventionally had higher prevalence than in pasture (P < 0.0001). Of all the isolates found to have resistance, 80% were from the Southeast. Of all the pasture isolates tested, 5% (8 of 162) were resistant to ceftriaxone, which is higher than previously reported from any production setting. None of the isolates from conventional flocks showed resistance to ceftriaxone. Multidrug resistance (resistance to three or more classes of antimicrobials) was found in 69% of the isolates from conventional farms and 11% on pasture farms in the Southeast (P < 0.0001), with the predominant resistance type of AmCSSuTeAx (ampicillin, chloramphenicol, streptomycin, sulfasoxazole, tetracycline, amoxicillin/clavulanic acid; 62%). About 5% of the pasture isolates from the Southeast showed the AmAxCFCRO (ampicillin, amoxicillin/clavulanic acid, cephalothin, ceftriaxone) multidrug resistance pattern. None of the isolates from Wisconsin were found to be multidrug resistant."

And here is a nice chart showing some important differences between commercial and pasture raised poultry...
