Mike I have had hatchings that I've had to assist feed for 10+ times before their metabolism really kicks in and their body tells them they must eat on their own.. I've had a couple that as soon as the rat touched their mouth they would coil it.. and swallow..
The fact that she is swallowing on her own is encouraging.. keep going like you're going offer live leave it over night and see.. maybe even skip a week or even two, she's gotten a couple of meals in her now..then offer..watch her weight when you skip if she looks like she's going down hill..step in again..
Animals like this can be saved and go on to be great feeders they just take a little more time and hands on care.
