I just posted about this problem the other day. I'm having the exact same problem with 2 out of 3 hogs. Having never owned them before, it's a bit disconcerting. I'm used to ball pythons not feeding for months at a time, but not any colubrids. My hogs are fairly small (like yours) so I didn't try and cool them or anything; just kept business as usual.
Its been about three weeks now for me. One of the three eats all the time.... I guess I'll just ride it out. Only one person replied to my post and they reported a similar occurrence. Sucks though.... not knowing.
I've lost baby snakes before and its never fun but its worse when its a new species for you and don;t know if you have all the facts. Maybe someone will respond with more insight. Good luck.
