I'm a beginner and I believe my duckling has Riemerella anatipestifer Infection and so far the symptoms Ive seen is the head shaking, scratching head and yawning alot and also the green poop. It still seems energetic as of now but the other duckling I had whom I believe had the same infection just died earlier. Please help!! home remedies are very much needed since I don't think I can buy antibiotics.
