Hi - anyone ever run across this before? Is it cause for concern? Only one of my Australorps, Sophia, has this among my small flock of four. She's had loose stools since she was about 4 weeks old... We live in a temperate climate (Southern California) so frostbite and/or temperature stress are nonfactors. I've wormed my girls twice with Wazine, all vaccinated for Marek's @ the hatchery. No improvement. Fed the chickens yogurt with probiotics and drinking water with ACV, slight improvement but i could have imagined that. Hens free range around our decent-sized property, roost up in a large chicken ark at night (cleaned every several days). They "graze" on our lawn and also eat my planted chard and broccoli (!) leaves; we feed them organic chick/developer pellets but treat them with mealworms, oats and sunflower seed / pepitas. Tried separating the patient for a couple of days, but she didn't really eat or drink vigorously until i returned her to the flock today (she was pretty agitated being isolated from her sisters). Now started all the chickens on Sulmet cocktail in their water as another hen may have loose stool as well. Sophia doesn't want to eat / drink apart from the flock (she was immediately eating and drinking as soon as I returned her to the flock), so assume this is "psychological" only). Any insight?? Thanks!
