Hi I have 1 yr old brown commercial layers and one of them has blood around her vent after laying an egg. There was also blood smeared on the egg. There is not a lot and she is acting fine otherwise. Just wondering if this should be a concern. I have separated her from my others till she can clean her self up but, would like to know if this could be more then I am making of it. She is eating and drinking normally and still comes at a run when she sees the "bucket" (treat bin). Any thoughts??
