New KSB's, neither will eat

Alright, so have two Kenyans, temperature on hot side is 95 at day, 84-87 at night, cool side ranges 87-90 during day, 78-81 at night. They are on crushed walnut. Small water to offer very modest humidity and drinking.
Ok, so going on week 4 today, neither will eat. I have brained pinky, offered smaller portions, placed 2 in a small tune to simulate a nest. Left them alone over night. Nothing. So any suggestions? Cause after a month I'm a little concerned.

Hmm... When are you trying to feed them (when do you offer the food)? Also, was their breeder feeding f/t before you got them?

I have 2 KSBs myself and although one was a slow feeder to start, they both pound food now. What I do with mine, is I feed them at night, around 9pm in a separate deli cup or rubbermaid box (started off with sand in the container, now both are on paper towel in their feeding containers). I put them in the containers about 30 mins before eating and place back in their tanks on the warm side of their enclosures. Then I feed using f/t mice wiggling it around to stimulate a feeding response. Now that they are both used to the routine, I don't have to place them in the containers so early, just right before I feed them.

I would also suggest not lowering the temps on the hot side of their cages at night. My hot side stays at 95 all the time. I also use a heat lamp to warm the air in the cage (it's an infrared lamp so it can run at night too).

Good luck!
