What is your husbandry like

Enclosure size, temps, humidity, hides etc.

At that size the animal was more than likely house in a 6 quarts tubs and I would recommend doing the same if not already done.

Use aspen as substrate this tend to do wonder with animal that are hard to start or will not feed.

Offer 1 six inches plastic flower pot saucer for hides.

Not handling, no staring just leave it alone for a week and offer a live mouse or rat depending on what food the animal was on prior to acquiring it.

There is no reason at this point to even think about assisting, patience proper husbandry and food are more than likely the key here.
