We found a very tame hen on a popular running trail not near any homes. We took the hen in and gave her a home. About 2-3 months have passed and she has adapted very well. She co-mingles with the dogs and comes running to greet us when we're home. She has not produced any eggs. She looks to be a Rhode Island Red or a Production Red. Our concern is the past 2 days her energy seems to have significantly declined. She is still eating/ drinking. Her tail feathers are also pointing down, and it is almost as though she has a hump on her lower back. Any thoughts or comments would be greatly appreciated.
