Our hen, Goldie, has been carrying around a hernia for several months. This morning we found her sitting on the roost in the coop with the hernia opened and entrails oozing out. Certainly, this is fatal, but I don't know what to do. Do I just let nature take its course and wait for her to die, or do I euthanize her--if so, how? I have never killed a chicken before and she is a beloved pet of my 11yo son, our chicken caretaker. Please tell me what to do ASAP!
