Besides the weird (probably lash egg) thing, she’s laid three eggs since I put her in the garage. One yesterday with a very thin shell which she apparently crushed in the process of laying it or shortly thereafter, and two (or two yolks anyway) this morning (I know... is this even possible?) with no shells at all. Her new puppy pad which I had just given her had a yolky mess on it
Do you have any calcium to give her? You can give Caltrate or even a TUMS for a couple of days to see if that hardens the shell up.When I came back there was yolk all soaked into the pad again. So I cleaned it up again.
It sounds like she's having some reproductive problems, hopefully it's just a glitch and things will work out. Feel her abdomen for any bloat or fluid.
