Found this on my poop tray!! First thoughts Coccidiosis? However none of my chickens have any signs no sickness ! They are eating , drinking and as active as usual in 30 degree weather! I’m literally with them everyday and spend time with them and nobody seems sick ! Would it hurt to treat with corid anyway even if it’s not that? How common is this ? I’ve never had it before! I use sand in my coops they are never damp and I clean everyday! This would also be a adult chicken that left this dropping! Please help i dont know what to do !
