I recently had a pregnant red tail boa die. The day before she died, I had noticed that she was "squeezing" her eggs as if she was trying to push them out. The only difference that I noticed was that a clear liquid was coming out of her that had a horrible smell. The next day i found her dead. I cut her open and revealed slugs that seamed to be septic. I was told that she was probably "egg bound". Is this a common occurance? What causes it? And what can I do to keep it from happening again? This was a very depressing experience.
