Agreed with Aapomp831. Sour crop will display stink and liquid coming from mouth. Hard crop doesn't necessarily mean impacted. When they eat that is where food is broken down. So check em first thing in morning.Hello. I recently noticed that some of my flock members had sour crop (really hard crops). What should I do? Any advice appreciated greatly.
While I agree with this treatment, just be aware that you should not massage the crop if it has soured. Only at the impacted stage does this work.When our birds have had impacted crops that don't empty by morning, we've had success by squirting a dropperful of olive oil into their mouths, then gently massaging the crop for 10 or 15 minutes. I try to work the crop contents up away from the wishbone area. It could be that whatever might be lodged at the exit point of the crop then gets rearranged allowing the normal emptying process to begin.
I've read that a long blade of grass, a wad of feathers, some other object could be responsible for the plug. I've never determined what exactly was the offending object.
Most often this has worked. A few times the whole digestive system had shut down. Understandably, that's not a good thing.
Good luck. Please let us know what happens.
