Hi,
I got a group of Kennerly from Mike also and at first I had the same thing happen to me.
I got one to eat on toad scent and by toad scent I mean cut open the toad and really rub the pink in there, if that doesn't work try cutting a leg of the toad and presenting that to the hog, if you notice interest and it's going after the leg, take it out and present it with the scented pink, if there is still no interest then cut a piece of the toad's skin and put it on the pink's head, do that for about 10/15 min at the time.
Also try the same thing using an anole or house gecko (One of mine eats that way) and always move the pink around as to peek the snake's interest.
Kennerly's get very stressed out so if you notice that stop and try again in 15 min.
Hope that helps you, these are awesome snakes
