Hi folks. I've been researching older posts, but not finding a definitive answer. This morning there was a lot of blood on one of the roosts and spots on the floor. I have 15 hens in that coop and all are running around, scratching, eating/drinking like normal. Nobody seems lethargic or ill. I checked them all out, especially the ones I know like to roost on that middle bar. None of their vent areas show any signs of blood. The only one who had a few red spots around her feet has no injuries that I can see and it looks more like transfer from walking through the bloody spot. Since the biggest pool was up on one of the highest roosts, I don't think they killed a mouse or rat--no carcass remains or other evidence of that. I was reading that sometimes an injury can bleed a lot, but am worried this is something internal. My oldest girls are 6 years old, and the youngest are 2. Any advice/experience shared greatly appreciated.
