Two of my chickens have/had runny poops, and are lethargic, sleep all day, trouble walking, falling over if trying to walk...I treated them for cocci with corid for 6 days. They seemed better atleast no more runny poops, still kinda lethargic. 4 days later they went back downhill, started treatment again. I'm on my 3rd day of treatment again and they still seem really lethargic. They both were covered in lice so I treated them with a bath of dawn dish soap and then dusted everyone in the flock in sevin dust. What else could it be? The bantam is only lethargic but no runny poops (that I've noticed), the standard has both symptoms. Do I need to clean the coop but then what about the run?
