With the hope of helping others I thought I would post how my avian vet treated sour crop! Early diagnosis will definitely help you when dealing with this. I caught Edward's within hours and was able to start treatment very quicky. Edward is a 1.6 lb Showgirl which you will need for proper dosing. The medicine for sour crop is: Metoclopramide 5 mg/5ml syrup give 2.5 ml every 6 to 8 hrs I would message this into the crop very gently (never turning him upside down, just took my 3 fingers and gently messaged the med in) Enrofloxacin Susp give 1 ml every 12 hours for 7-10 days this is the antibotic. Electrolytes in the water (I uesd watered down gatorade) Dr. Hoover also put him on a soft diet of Lefaber's mix (the crack in chicken world I guess) he went nuts and it gave him the extra boost of energy he needed. The Lefaber's mix has to be served warm every 2-3 hours mix 3 scoops with 10 ml water, it will look like a warm milk shake. (I added Probois to counter the antibiotics) I was fortunate enough to only have to force feed one time and am very thankful for that. Dr. Hoover also told me to keep him inside under a heat lamp which is where he still is recovering. I highly suggest adding all of these to your emergency kit. I know this is what saved my babies life. When my Edward came down with this I didn't waste anytime in getting him treatment I have only ever lost one bird and it was to sour crop. I am thinkful to Dr. Hoover in Murfreesboro Tn and sugget him for all your veterinary needs if you are in this area. He treated my Chicken as a beloved pet. Which he is! I am very thankful to have him within an hours drive and will not hesitate to use him in the future. I have just read so much contradicting information on the internet and didn't know how to treat him myself and Edward's life meant too much to me to risk it. I am very happy I sought a professional and so is my Edward. I do hope this information helps save more lives.
