There are many options...live, brained, scented, de-scented, teasing... You just need to find what your hatchling likes. Don't be afraid to try something new that you just thought of and definitely try each option more than once. I am currently working on several problem feeders (again) and just had 2 eat a live pinky that I teased them with. Both have been offered live before and both had been teased before, but the combo worked. Vary the time of day (some are day feeders, some only at night). Remove their water for a couple of days and offer a wet F/T pinky. Try a different source of your pinkies (some absolutely refuse to eat what I produce here but go crazy over RodentPro pinkies and vice versa). Take your snake for a drive (a good one, maybe half an hour or more...I will put them in a small snake bag and in my pocketbook and take them grocery shopping to make up that time). Just don't give up, but don't over-load your snake by trying too often. And I hate to say it, but there are some hatchlings that were just never meant to survive and will never eat.
