knobolichi eating problems

I have three knobolichi hatchlings that are not eating by themselves. I have been force feeding them since July or August, so they don't look terrible but they are underweight. Any hints to get them eating?

Thanks

Were they ever eating consistently? If so, how many times?.. A lot of North American colubrids will go off feed during the winter months regardless of what temps you keep them at.. If you are still concerned you can try feeding live day old pinkies, braining pinks, or try scenting a pink with a dead anole or fence lizard. Wash the pink off good if you try this method. I have a picky eater that did not start eating for almost 2 months after it hatched.

They have not eaten by themselves at all. I put them down for brumation about 3 months ago to see if that would start them eating. They started looseing weight so I brought them up, but they still have not started eating.

Not sure why you would brumate non feeding hatchlings? Brumation slows their metabolism and usually triggers hormonal changes. Hopefully by now you have them warmed back up and are offering prey items every couple days. Good luck getting them on track!
