Today my husband found my son's amerucana standing alone with blood all over her face and underbelly. When he didn't see one leg he immediately called me (not one for blood). At first glance she looked rough, but on closer inspection I found that she had her other leg tucked up. She was missing a toenail and had apparently scratched at her head, but we found no other injury. I cleaned and wrapped her toe and put her into the hen house where she has just been sitting. My other hens are not bothering her (they free range) so I thought she would be fine without being separated. Based on other posts I am surprised that she is so quiet and inactive. Most others seem to say their chickens continue to act normally, so I am beginning to be concerned. I am still new to chickens and I am wondering: should I be concerned and do something else or could she just be a bit more "sensitive" and just need some time?
