Its not uncommon, I had one little guy that was a little bit slower than all my others. I waited to offer food until 1 week after they shed. I started half the babies on hopper mice and half on rat pinks. Here are a couple other ideas to try before force feeding. Don't offer food every day. Offer food, if its not taken that day, wait 5 days to offer again. you can put the snake in a brown paper bag with the food item and leave it alone for a while. Also, I've never had to do it, but there is force feeding and assist feeding. There are some videos on these techniques. Look on you tube for BP feeding. Some people I've heard will dip chicken stock on the prey, usually for F/T feeders.If all else fails you can take it to a vet and get it checked out. Be patient, it will probably eat.
