I just took some cockatiels in from someone that could no longer take care of them. and seems 1 has a problem.She has something hanging from her rear.Looks like maybe her rectum, its cherry red she looks fine and acts fine but just happened and scares me. I live out in the country and we have no birds vets around.Is this something thats gonna kill her? Is there anything I can do? They tell me she has been laying eggs over and over and last 4 eggs has had no shell.Any help please and thank you.
