Sour Crop

Sour crop is a condition of yeast infection in the crop leading to thickening of the crop wall, dilation of the crop and birds losing condition and possibly dying.

The cause is often difficult to determine but you should check the condition of the feed store and always ensure birds have fresh feed. Treatment is also difficult as there is no specific treatment for sour crop.

The use of copper sulphate has been successful but this must be carried out under veterinary supervision. Manually emptying the crop is difficult and the underlying fungal / yeast infection needs to be controlled. The crop can also become impacted in which case removing feed and manually massaging the crop is of use. In many cases a dilated crop is difficult to treat and the prognosis is not good.
