Here it goes...got white Cobbs (meat chickens) in begining of March. Never had chickens before. Wasn't raised on farm. Was not aware of what to look for with chickens getting sick. I've researched a book called Chicken Health after I started seeing sick chickens this Thursday, I lost 1st one. Lost one last night & another today. Im pretty sure they have Coccidiosis. I've read about it on this site as well. It doesn't say how to clean pen or even hen house. Can anyone give advice on cleaning. I'm worried about if I use a bleach on ground for bloody stools. Will it bother chickens? I have eight chickens left. But.....I also have Isa Brown flock next door to Cobbs. Im not seeing any signs of illness in them. Worried I will have to extinguish Cobbs if they keep dieing. I hate seeing them struggling like this yet...I keep hoping for them. One of the roosters that was sick this morning was much better looking this evening. One of the other roosters that was fine this morning, was the same one I found dead that same night. Can anyone advise?
