Lazy Gardener, Thank you. There is no visible issue now, but I do have a hen that's showing signs of being sick. I'll check her again tomorrow and see if there is anything out of the normal. She does have "runny" stool on the rear but no worms.
I currently have 40 hens, 10 are several years old and 30 are two months old.
I let then free range on the weekends and evenings when I am home.
For the most part I'd say they are fairly helathy. A few years ago, I lost 4 or 5 within a 2 month period .
All seemed slow, and sitting in the corner...
