I am hoping to get some insight into the best way to disinfect not only the coop ( a large 6.8 dutch style coop), but also the ground in the roughly 900 sqft run. I've been struggling with what we believe is coccidiosis since the summer - I've lost 4 birds since August - 2 this week. Here is what I've tried already: 1) I've treated multiple times with Corid 2) I've had one of the birds sent off for a necropsy to confirm since they were not presenting with the "typical" blood in stool. Result was 2 strains of coccidia resulting in a secondary necrotic enteritis. 3) We've had a hard time keeping our run dry with all the wet weather we had all summer, so we raked off the top layer of soil and added about a foot of wood chips over the whole area. 4) Cleaned out coop replaced with fresh bedding and completely replaced the roosting bars. 5) I clean all the poop out of the coop every morning with a dog pooper scooper and dispose of it Lost my 2 Black Copper Marans this week, after treating with both Corid, and tetracycline for secondary infections. Based on the incubation period of coccidia and the fact that I've been struggling with this for months leads me to believe that there is a secondary point of infection that I am missing. If someone can recommend the best way to disinfect the coop and run area (including the soil) it would be very much appreciated.
