I'm sure this question has been brought up before but since I have a picture I thought I might receive a better response. One of my Red Star's was not feeling well about 3-4 weeks ago so I brought her into the house and after a few days she bounced back. I did pull out something from her vent couldn't say what it really was except part of an egg. Since that time she has dropped a few yolks no shell or a completely collapsed egg. Could someone tell me what the issue might be and if any treatment is available to resolve it? Thank you.
