ive been reading up on sour crop and other things, just so i know what to look for and have an idea of what to do, and im getting mixed messages about sour crop. after some reading about it i checked my hens crop lastnight before bed, some of the were pretty big and soft. i understand this is where food is stored, but on a few chickens the crop was fairly large. how do i know when its sour crop? will the crop always be hard when its sour crop? my chickens free range and always hae access to their feed and water in the coop, i also have a water bowl outside by the coop as well. some people make it sound like that if their crop is big its sour crop? am i reading to much into this?
