Very interesting article, thanks. I was just curious, because the pine shavings in my smaller coop tend to get wet easily when it rains and I certainly don't want to go through what Wynette has been dealing with.
I have been following this thread... here some more info:
AVIAN INTESTINAL SPIROCHATOSIS

EXCERPT:
causes chronic brown watery droppings...previous studies have shown that 70% of flocks have spirochaetes but only 30% have pathogenic or disease-causing strains."

excerpt:
B.pilosicoli is potentially a serious chronic pathogen...faecl contact is the major factor in the spread of the infection...studies show that tiamulin is particularly effectivce as treatment .

Both the tiamulin and lincomycin treatments were effective in removing the BP infection, while untreated infected birds remained infected. The use of zinc bacitracin in flocks with avian intestinal spirachaetosis (AIS) caused by BP should be avoided. However, if the infection is caused by B. intermedia, zinc bacitracin is effective in reducing colonization. This emphasizes the importance of differential diagnosis between the two species of spirochaetes in flocks with AIS.

"This project has improved the Australian capacity to rapidly identify and type intestinal spirochaetes from chickens. It has demonstrated that strains of the various spirochaete species vary in their susceptibility to antimicrobials, but in general there is little antimicrobial resistance present. Care should be taken with the use of zinc bacitracin, as it may predispose chickens to infections with B. pilosicoli. Both tiamulin and lincomycin are effective in treating intestinal spirochaete infections, but addition of dietary enzyme with xylanase activity also can reduce colonisation with B. intermedia."
you/your vet considered this possibility or tested for it?:

(excerpt)
"...Species of the genus Cryptosporidium are coccidian parasites that infect epithelial cells (extracytoplasmic) of the intestinal and respiratory tract of vertebrates (see Opportunistic Infections). Although immunocompetent hosts show no or only mild clinical signs after Cryptosporidium infections particularly young birds under stress may suffer from life-threatening watery diarrhea, or severe respiratory symptoms. Cryptosporidiosis in chickens, turkeys, quail, and pheasants is usually manifest as respiratory disease caused predominantly by C. baileyi or as enteritic disease (small intestine) caused by C. baileyi and C. meleagridis. The severity of infection depends on the immunocompetence of the host. Infections are due to aerosol transmission of infective oocysts coughed up by carrier (seeder) birds, or may be transmitted by feed or water supplies containing sporulated oocysts derived from feces of infected birds. Clinical signs in birds are coughing, mucoid discharge, dyspnoe, diarrhea, dehydration, weakness and weight loss.
Causal therapy and chemoprophylaxis of chicken cryptosporidiosis with ionophorous antibiotics is problematic. Many approaches to anticryptosporidial efficacy of commercial drugs have failed to improve symptoms in birds suffering from Cryptosporidium infections. Several other anticoccidials as sulfonamides, lasalocid sodium, halofuginone, and decoquinate, or other antibiotics (e.g., paromomycin) available as additives in-feed (Table 1), or as other dosage forms for oral administration have proved to be insufficiently effective in controlling or even eradicating Cryptosporidium infection in birds. The drugs may exhibit positive short-term effects such as improvement of watery diarrhea and reduction of oocyst output in feces due to their `static' rather than `cidal' action on cryptosporidia."
