i went outside to open up for free range this morning and I noticed one of my laying hens has blood dripping from her vent!! She won't let me catch her and I can't get even close enough to look under there and try and see what's going on! I'm so worried about her. Does anyone know what this could be and what I do? I have some corid left from when my silkie was sick. And I treated the rest with preventative dose for 2weeks after my silkie passed. Should I give her a dose of that? The rest are all healthy as can be and happy. I'm at a total loss here and I'm totally clueless as of what I should do! I have never even heard of a bleeding vent! Can someone please help?
