Ive had this hen for 2-3 yrs. and within the last week she has become ill. There is a lg mass on one side of her stomach. I dont think its a egg, she would have passed by now if it were. I know there is somthing else that happens to older hens. I have brought her in the house and made her comfortable. I feed her evrey 2-3 hrs. I will not just let her die. I assume she wont recover, she will not get up. She doesnt seem like she is in pain, but id rather do all I can for her and let her go on her own then put her back in the coop to suffer and die alone. Any thoughts or suggestions, id appreciate it, thank you !
