I had a 3 year old silkie hen who appeared lethargic before the weekend but was still eating and free ranging. She was just slow moving. I had given her a warm Epsom bath and vitamins. That seemed to perk her up. Monday, she was off again. This time I noticed her squishy belly when I soaked her. Again, she perked up and was acting fiesty and normal but I made a vet appointment anyway due to the fluid in her belly. Really was thinking water belly. She was full of tumors. The vet said cancer and that she had tumors from her crop down. He couldn't believe she survived as long as she did. He told me he couldn't say what caused the cancer but I shouldn't worry about my other girls. I am still concerned. Anyone have any experience with this? Has anyone heard of this? Last year we put a hen down due to suspected egg peritonitis but now I am wondering if maybe she had tumors.
