One of my ladies seems to be having a hard time. We have been keeping an eye on her the past week. I found one egg without a shell or membrane at all in the coop, and thought it weird. Today I went out to put them up and found her alone sitting, tail down and a shell-less membrane-less egg behind her. I brought her in and put her in a warm tub with Epsom salts. She pooped and had a white soft thing that looks like a membrane with some albumin in it (pic). Ideas? I've been giving calcium citrate the past week.
