Last night I found one of my silkie hens sitting on the floor of the coop, thinking she was broody, AGAIN, i reached down and picked her up, as I did liquid started pouring from her mouth, I took her outside and held her upside down and it continued to pour. I put her back in and repeated the same before dark. This morning she was up walking aroound again. Could this be sour crop? It did not smell nor was her crop swollen. It just felt squishy.This is a first for me. Ideas? More treatment needed?
