I put together a series of pictures of axolotl egg development. My eggs last year always hatched at two weeks- they were warmer. The room temperature in the basement vs the main floor in our house is about 5 degrees different. The upstairs stays around 70 degrees vs basement 63-65 degrees. My 2015 eggs had about a third hatch at 14 days with the majority still in eggs on day 19.
