Actually free range birds, like children in daycare, face more challenges to their immune systems, and it's those challenges that build up strong immunities. Research shows that kids that attend daycare as infants/toddlers contract fewer communicable diseases over their school careers than children who start school later. The explanation ... their immune systems are challenged when they are at their peak of development, and therefore the immune response is stronger and lasts longer. I haven't seen any research done specifically with chickens, but several studies have shown that pastured pigs have fewer parasites and contract fewer diseases than their penned counterparts. Blood samples on study pigs showed that the pastured pigs ... exposed throughout their lives to parasites, etc., had higher levels of antibodies to common ills, higher resistance to blood-borne parasites, and healthier gut flora (more resistance to parasites) - than pen-raised study pigs. Another recent study demonstrated that "pasture only" equines that were given adequate forage and a minimum of external "additives," INCLUDING chemical wormers, also had far more active immune systems than barn-raised, rotationally wormed counterparts. I can't imagine that this same principle doesn't hold true for chickens as well. I'm not saying stop worming and treating ills as necessary, but it sure seems to me that an increasing amount of evidence suggests we humans are fixin' things that ain't broke! We've become so soft ourselves and developed such an adversarial relationship with the environment that we just assume our animals are the same way. But I never saw a chicken that simply couldn't do without air conditioning, hot water, and a big screen t.v. ... we humans aren't nearly as smart as we think we are ...
