Congratulations to you & Pearl. That is a lot of babies to hatch out. In the wild where would they lay their eggs & would they guard them against prey? Could Pearl absorb the egg that hasn't come down back into her system? Are the eggs soft shelled like turtle eggs? I hope Pearl will pass her egg safely.
In the wild they lay their eggs in a sheltered area and hen leave them. Unfortunately, it's unlikely for her to reabsorb the last egg at this point, it will have to come out...with any luck food/swimming/massaging her will push it out without the need for drastic measures. Yes, the eggies are soft like turtle eggs. Good eggs are white and fluffy and feel like marshmallows. The dud egg she laid was yellow and squishy.
