i dont think lack of grit was the problem in this case....it dosent make sense to me... because,if they were not getting any food from lack of grit grinding up their food..wouldnt the food still be stuck/impacted in the crop?....
... so,if the birds arent crop impacted..the food was getting into their digestive system.**chickens digestive systems confuse me!...with crops and gizzards...
.**.......i think it sounds like worms....also..i was always told that you did not need grit if the birds were JUST eating their chicken feed...its when you add the differant foods that they need the grit....is that right or not? now ya got me wondering....
