I was out feeding the quail and came across a little hen with a strange looking head. I brought her in and she is away from any males for now. Im pretty sure the sack on her head which wiggles when she moves her head is filled with blood. She doesnt seem to be bothered by it and she can stay with me at least until the blood is absorbed or Im wondering if I should make a cut and drain it? Any advice on this is welcome.
