I have a 2 year old hen that has been slowly declining. Her comb is pale and she is lethargic. She had what looked like a stool scald on her behind and we have soaked her in a warm epsom salts bath to clear it up & treated the area with Betadine. Yesterday, I decided to separate her from the rest of the flock & noticed her stools are VERY WATERY. I had the vet check a stool which was negative. She was eating yesterday, but not so much today. I have given her some polyvisol that I had on hand when we had chicks. What else can I do to nurser her through this. She's more of a pet than a layer at this point and I DON'T want her to suffer. Any suggestions?
