The crop is almost always on the left. The bulge in his chest, if it's the crop, should be on the left, and sort of soft, malleable; you can usually feel the grains etc within the crop from touching it on the outside. If he's not losing the cropful overnight then he possibly has a tumor or blockage.LOL Thanks for your response. I think the right side of his breast is bigger than his left. Something just doesn't seem right.
