I don't know why my two hens have lost their appetite. They used to look forward to eating their greens in the am, and layer feed during the day. They free roam during they day. In the evening before they go in their run I give them a little scratch, they arn't really interested in that either. They don't act sick and drink water. They haven't had a first molt yet, think maybe that's it? Their 15mths old.
