How to Treat for Soured Cop in Chickens?
Try not to feed your hens, particularly bantams and smaller breeds any food that is large as this can easily cause a blockage, even very long blades of grass can get stuck and cause a backup of food in the crop.
If you’re hen has a blockage in their crop you will need to flush it out, we would advise seeking professional veterinary advice before attempting to flush the crop yourself, if you are fairly confident the process is explained in detail here (link to Blog Post).
You can also find videos on YouTube on how to do this process.
Flushing is by far the best way to treat a soured crop; however, some try to treat with natural remedies that are given to try and break up the blockage internally. Although this can be effective, the best course of action is to remove the infection and blockage rather than try and treat as the hen would then just be digesting old food that has been stuck in her crop and this can then lead to further digestive issue.
If this is not effective and your hen still has a blockage then seek professional veterinary advice as they may need a surgery and antibiotics to remove the blockage.
