I would begin with the assumption that you're dealing with an impacted crop. You can often treat that while cancer and bowel obstructions approach the realm of futility, although treatment for crop impaction can often resolve bowel obstruction caused by back up poop (constipation).
You can use any sort of edible oil or mineral oil, but I prefer coconut oil in its solid form because it's easy to get into the chicken without most of it ending up on you and the outside of the chicken.
Taking about two teaspoons of oil to start with, slip it into the beak. Or the chicken may even happily eat it off your finger. Then massage the crop gently for a couple minutes. You may feel the contents break up and disappear.
If not, introduce another teaspoon of oil and repeat the massage. Repeat a third time a half hour later. If after waiting another half hour after the last massage, the crop is still full, you may then give a stool softener such as Dulcolax, something with no stimulant. Wait an hour and do another massage. That should empty the crop.
If not, surgery may be the last resort, which we can walk you through.
