Ok man I found the recipe for the millworm slurry .... Breeders have been using this stuff for years it really helps them man.
In a blender, combine: 1 small can Hill's A/D pet food (available at most vets)
1/4-1/3 cup Ensure (not chocolate)
1 jar baby food squash -
1/4-1/3 cup Pedialite
2 crushed tablets or contents of 2 capsules Milk Thistle (herbal supplement, liver purifier, found at most drug stores.)
1/2 tsp. each calcium powder and herp vitamin powder -
1-2 extra large handfuls of mealworms
After you blend all this up get a syringe with no needle on it and feed him a little 2 to 3 times a day or night he should get a little energy back once you get a little of this in his gut.
