Last week a noticed a lump on the right side of my 21 week old Black Sex Link "Ethel" I felt it and it was kind of soft. Took her to the Vet and he did not do much but gave me some probiotics to put on her food and watch her. Next morning her crop felt hard so called the Vet again and brought her in just so he could see how hard it was. So per him, kept her in house during the day and just gave her chicken food & water so we knew what he she was eating. I gave her a little Mineral oil and massaged her crop. Put her in hen house at night so she would not get to stressed and only water available. Next morning her crop was empty! I was so happy, thought she was better. Let her back out with the other girls and she seemed fine. later I checked and the crop had stuff in it which I know there should be some but this seemed heavy and a lot. Watched her and saw that she was eating sand, which is the floor of our coop. I understand they need grit, but her crop is now full and hard again. I don't know what to do, Someone please HELP!
