I have another hen with different issues. My 7 year old Barred Rock is very gasy. That's right gasy. Her crop is perfectly fine with no signs of impaction or sour crop. She's also pooping normally, though this last day or so her and another flockmate had a few loose ones with bits of what looked like intestinal lining or dried blood. (Possible coccidia?) No sores, sneezing, water belly or any other issues. Just gas. She's been very alert, talkative and overall perky. Her weight is also good. I'm currently giving her and the others yogurt with probiotics and Corid. Also, started treating her for possible sour crop yesterday. The gas doesn't smell fermented like sour crop. Instead it smells like garbage or badly decaying compost. One of her flockmates has stools that smell like her breath. Although, that one has no gas and seems fine otherwise. The gas seems to be coming from her intestines. Since chickens don't fart, I assume it's just coming back up. She also has little to no gas a few hours after she's eaten. I change their food and water once or twice a day. Also, I have been as diligent as possible to clean up overripe/spoilt fruit dropping from a nearby tree. Has anyone ever heard or experienced this type of thing before? Any possible treatments?
