In reading about chicken diseases, I see the symptom "loss of thrift" or "lack of thriftiness" often listed. What does that mean? I looked in your glossary above and didn't see it, plus the dictionary seems to indicate that my hens may be prone to frivolous spending (ha ha). If I am checking my hens "thriftiness," what exactly am I looking for? The wording seems to indicate something about their appearance (or should I be checking their closets for too many shoes, more ha ha ha)...
