I planned to try live with him this weekend - and I appreciate your feedback; I was thinking that I'd have to feed live. When I've had to do that in the past the snake usually ended up accepting F/T soon after but they just needed the live prey to get them started. And yes, whenever I feed I thaw the rodents/birds in the snake room, plus I use a hair dryer to really spread the scent around.
BUT! The trick shared by the Colubrid importer worked!! I used collagen casing to tie a quail reptilink to the body of a day-old quail and he ate that. I also injected the reptilink with some Carnivore Care for a nutrient boost. I won't rest easy until he has taken a few meals like this, but for now I am just hugely relieved that he actually got some calories in him. Next feeding I will try two quail + reptilinks - that should be a very good meal. If he starts refusing that, I will definitely go to live.
