I just got my neighbors last hen, the rest of them were killed by a fox so I agreed to take the last one. I dont know what is wrong with her it has been a week and she just sits around with her tail down and stays puffed out. I have no idea what this could be but my very little research is saying she's eggbound. How do I fix this and how do I get the egg out. She is 2 years old as far as I know.
