Hello All, I go outside to my coop to lock up my girls for the night and notice one of them has blood in their vent. I watched her and the poop came out fine, normal, no blood. But this wont go away. I dont know if its part of her vent. Help please. Shes almost one and shes a road island red and its march 19th just getting over winter in New Jersey. She lost all her butt feathers. What can this be? Help! Panicking!!! Thank You So Much!
