It's been a long time since i've raised buttons, but I remember sometimes they could take 18 days to hatch, depending on as @JaeG put it so well, the journey they had.
Don't despair that you're having a tough first hatch. My first hatch was fine... the 3rd, 25th, and 80-ish ones (I've lost count, just making up numbers here) maybe not so great. The point is that glitches and rough patches with incubation happen to everybody; don't get discouraged and give up.
Give the farmer batch a couple more days. If there are no external pips by late on day 18, I'd say they're done. Hopefully you get a bunch of fuzzy little bumblebees from the ebay batch.
