I treated my young chicks and guineas for cocci as I lost 2 and noticed the symptoms. Everyone perked up and then the other day I noticed dirty vent on a young pullet (most turned out to be roosters). I really want to save her. I have isolated, washed the area with warm water and dettol mix, pushed back in a couple times but it keeps protruding. She looks like she is straining but from the diarrhea ?
