I have one hen I really wonder about sometimes. She is an incredibly poor layer (as in I get an egg from her maybe once every 3 weeks to a month-she's my only blue/green egger). She seems to always have poo on her bottom...it's gross (it's been the same for months now). She is super flighty so examining her can be hard (though not impossible). She doesn't look particularly thin or act lethargic. We did have an awful wet gross spring here, but right now it's bone dry and extremely hot. She free ranges daily in a fenced yard. I've never wormed my girls...but this one makes me wonder if I should? Any ideas?
