Cynthia,
Sorry to hear about your bird.
If you get sour crop/ impacted crop in a fowl again try Crop Bound Capsules, you get 25 capsules for $4.95 and heard they work very well.

Also follow the Crop Bound Capsules with a dose of tetracycline, just be sure the crop has unbound and ease the bird back into feed, you will want to provide some yogurt or probiotic as the tetracycline will clean out the good with the bad bacteria.

I'm really amazed at what you've done for your chicken and I hope you'll keep us posted. I had the same problems with one of the 2month old Barred-Rock hens that I got from a friends farm. Her crop was impacted but I was able to massage her crop and feed her olive oil which worked wonders and she turned out fine. Where did you learn to do this? I'd like to know in case it happens again with my chicken. Thanks :)
