One of my older hens has a sour crop. I've gone through this once before a few years ago, so I know I'm supposed to give yogurt with live cultures. We don't have any, so I gave her some powdered acidophilus in some cream with a syringe. I did a search on here and found this link http://www.1976design.com/blog/archive/2004/04/16/sour-crop/ and followed the steps for massaging her crop. I gently turned her upside down and massaged, and all the yuck stuff came gurgling out. She was very good through it all. Right now she's standing, sickly like, on a pile of hay that I put down for her. Is it ok to keep using the acidophilus in cream or should I try running downtown for some live culture yogurt? That link said they used olive oil as well. Should I use that, or is it just fine without?
