How are you measuring your temps? How are you providing the heat? How long was your little break in period?
And you tried a f/t. How did you heat it up? I notice the warmer I heat my f/t rats up. The more agressive feeding response I get. My ball python and bood python both eat in shed. Some snakes won't though.
And with f/t are you using tongs and making the mouse move around and hop around so to speak?
I don't know the heating requirements for these snakes. So I can't tell you your good or not on the temps. But too hot or cold of temps can make em go off feed.
