When you have a number of neonates that are reluctant to feed on pinkies(ruthvens do eat pinkies) You must look at your husbandry, and possibly adjust it. The snakes are telling you something is not right, your task is to listen and do something about it.
There are lots of people hatching and raising ruthvens kings, are they all having problems with all their babies??
Check for the basics, temps, to much dehydration, not sufficent humidity levels(those last two are totally different things) security and mental fitness(not out in the open and scared to death(coming soon).
I am suppose to be very good with captive reptiles(other people say so) But when I have a problem, I look to myself and not at the snakes.
Of course if the neonates are small for hatchlings, or skinny(did not absorb the yolk) of deformed(kinks) those are good reasons for a neonate to be a reluctant feeder, but those are also the keepers fault. So I suggest go over your husbandry, show picks of how they are set up, maybe some one could offer some real help.
Also, anoles are horrible(hehehehehehe) if your from the east, try those little brown ground skinks, the ones at the base of cypress trees, they are similar to skinks found where these snakes occur. Cheers FR
