Your temps and humidity seem to be right on. Did you give her at least a week with no food no handling. If she is used to live offer her a live pup, if she eats it, then feed her live till she is well established and eats for a couple of months, then try a ft again, switching can be sometimes very fustrating. I have a girl that ate live from her breeder, I thought i had her switched to ft after she ate ft for a month, but then she just stopped eating, after 2 months i offered a live pup and she ate like she was starving, so i feed her live . I might try switching her again to ft, but some just won't make the switch.
