Yes, starting with a couple of doses of coconut oil would be what I would suggest. Two teaspoons per dose, then massage the oil into the crop, trying to use your fingers to break up the solid lump.
If coconut oil fails, then you can try a flush, beginning with a mild molasses flush and if that doesn't work, doing a three-day Epsom salt flush. These flushes are really the only thing to try if you suspect an impacted gizzard.
