Blu is a 5 year old hen , today i found this wound unsure what to do any advice would be greatly appreciated. Info about blu she hasn’t layed this year yet I assumed that was because of age and because she was showing symptoms of waterbelly , but shes still eating and drinking she moving around normal , I treated the wound with vetricyin. Her sister from the same clutch passed from water belly last year. Again any advice would be appreciated, thank you have a nice day.
