My set up: 8x8x6 coop with attached 25x6 run. My Roo is over 6 mos and started with bloody stool about 3 days ago. The youngest in my flock is 20 weeks introduced 6 weeks ago (by slow integration over 7 weeks), the rest are older, I have 20 in all. I have not introduced any new chicks, we do have one broody hen however that just hatched one chick a week ago. There is chick food in the coop for the chick and some of the hens are pecking at it. I have an adjacent coop and run with 3 BBW turkeys in it. I suspect the Roo and I suspect Cocci. I checked all the hens' vents and they all look good. All the chickens, including the Roo, are energetic at the moment, without breathing issues, eating normally and roosting at night. The Roo is crowing and managing the flock as normally. The chickens do not free range at the moment, due to predators migrating through the area. My questions: Could it still be Cocci? Or am I barking up the wrong tree? How fast does the disease spread? What is it caused by? Can it just show up without the introduction of store bought chicks? My last question: I'm pregnant, is it safe for me to be around chickens with this disease and to handle Corid? Thanks all!
