We have a 2 year old hen that doesn’t seem to have any obvious physical problems, vent is good, feet are normal, poop is watery, but she’s losing weight and hasn’t laid in a few months and we can’t figure out what’s going on. Her breast bone is very pronounced because I think she’s malnourished. She seems to be eating ok but doesn’t seem excited when we give them snacks like the rest of the girls do. Any thoughts or suggestions would be appreciated . Thanks
