If it was not empty after 12hrs he is having some crop problems.This morning his crop was like a small squishy balloon. He had not eaten or drank anything for more than 12 hours. Does this mean his crop has some kind of blockage?
He is definitely getting worse. No crowing this morning and sitting down with eyes mostly closed. His poop is black bits with the same yellow.
He is drinking a lot of water now. I have not given him food today because of the crop worry.
