Yikes, he had a awful start with that shop- pinkies are too small for even a hatchling BP & force-feeding is best avoided. He does look a bit thin in above photo, but hard it's to gauge well from just one photo, & at that angle & distance. Either way, understand that hatchling BPs (& other kinds of snakes too) can often look at least 'somewhat thin' because they grow incrementally longer, so they keep eating but don't appear to have gained any bulk (ie. width).

Also, remember that snakes are "designed" to be adaptable & even to grow slowly with meals that may vary a lot in the wild- the best thing for you to do is keep him eating realistically-sized prey on a regular basis. It would be nice to have a weight on him, to better judge what the best size prey for him is right now, but not if weighing him will cause stress that puts him off eating. What I'm saying is there's no "emergency" here- he's still new & settling in- so do what you can to keep him comfortable (as evidenced by him eating) without scaring him. I know that when you're new to keeping snakes, everything seems like a big deal, but it all get easier for both you & your pet...in time. Neither his size or his meals need to precisely match a chart, no matter how much it may seem that way at times here.

Charts are only there to help guide you. When you weigh a snake, OR when you compare their shape to a chart, it matters a lot if they just ate & haven't defecated, versus when they're "empty", or also if they're stressed -many snakes hold in a deep breath & appear to be bigger, or better fed, than when they've relaxed.
