Orally is how I do it.Update: they won't eat the mealworms with the vitB on them.So, I opened their mouths and tried my best to get 1 ml down them. I'm hoping it will help. We gave them some time in the yard today so hopefully that helped, although the WH want to sit after about 10 steps. We might put them in the bathtub and just let them swim tonight. I'm assuming that will help too?
