Last night my husband said he saw water come out of one of our hens mouth. I immediately thought of sour crop. This morning I checked her crop before she ate or drank and it felt completely normal. I didnt smell any sour oder coming from her. She is eating, drinking, laying eggs and free ranging with the other girls like normal. Should I be concerned and treating her for sour crop? Or is there a possibility that it was just a random thing?
