Hi backyard chickeners, I just got 2 new 6wk old chicks. Found blood in one of their poos. Tested positive to coccidiosis. I have been searching and searching ol Google and can't seem to get a few questions answered, maybe you can help! •How long do the oocysts survive in the soil? I've read up to 600 days!! If this is true it brings me to my next question.. •how on earth do you decontaminate the soil? Dig it all up? Turn off all Sprinkles and dry it out? I am so spooked by what I've been reading I feel it's a hopeless case! •once a chicken had been infecte and taken the antibiotics, CSV they get it again or rather more will their gut lining get destroyed. Or are they just carriers that will infect other birds, but be OK themselves. I'm very confused. The vet I had didn't know that much. (I insisted he test the droppings I brought in from my chicken even though he said my chicken looked healthy. Low and behold - positive for coccidiosis.) Getting antibiotics ordered in and in the mean time treating all my birds with medicated water for secondary infections that might arise. (Australia is a very affair to get medication for coccidiosis). I'm so worried about my 2 original chickens. They have been exposed to the new chickens droppings. ANY help, tips or info that you have would be a massive help!! Hopefully my spelling is ok. I'm writting this on my phone and it goes wild with the auto correct.
