My chicken has been sick. Very lethargic, runny, smelly green diarrhea, droopy wings. Hardly any movement. Eyes are clear though. Her crop has had stuff in it when she wakes in the morning. It is like she isnt digesting anything. I have been treating by massaging her crop and feeding olive oil by dropper. She has a comb that started to turn blue and now is almost all a blueish tint. This has been going on for 2 1/2 days now. I started her on 20% amprol powder, administered by dropper this morning. I have tetracycline and with go looking for some of the blackhead medicine this afternoon. She has been so healthy this last 9 months. Her coop mates are all extremely healthy and vigourous. Even the 9 month old cornish cross we kept as a pet and is now 18 pounds. I do not know what to do. Can I give her all the meds at the same time or is that grren smelly poop and cyanotic comb a clue as to what I should give her. She is not eggbound, checked that first off. I really need some help folks.
