I have a pullet with cocci. There has been blood in her stool throughout the morning , bloddy diarrhea is what it looks like, and she's been lethargic but is still drinking. Is there any thing other than cocci that can cause bloody diarrhea ?I have Sulmet on hand and hubby will be getting Corid for me this afternoon as the place that carries it is 30 miles away near his workplace. I had another pullet acting lethargic yesterday and that set off red flags with me so started treating the flock with Sulmet yesterday. The other pullet is back to normal today, I pray my sick girl will be able to get through it. My question is when do I start cleaning out everything? Do I wait for the cocci to run it's course or do I start cleaning out now? I use sand in the coop and the run, do I need to take out all of the sand and replace with new? We let them free range in our back yard a few hours a day, what do I do with this area? Is there any way to clean it? I have ammonia ready for cleanup. Thanks for the help.
