Hi there, I have only been keeping hens for about 6 weeks, so am very news to their ways. In the last few days one of the girls seems very lethargic and uninterested in anything around her. She will sit or stand in the same place for hours on end. Her back end is pointing down to the floor and not lifted so it looks like her back is smiling (if you know what I mean). The other two are eating everything they see, but she appears to be off her food too. They are all about 22 weeks old and the other two have just started laying. If you have any ideas or suggestions I'd be very grateful. Thanks.
