There are two types of Epsom flushes. The quick one is one-fourth cup water with one teaspoon Epsom salts. Have the chicken drink it all or syringe it into the crop. This is mostly for a quick fix for an obstruction, not to treat yeast.
The better flush, more thorough, but more effort and time, is the three-day flush which needs to be tubed into the crop. The solution is one-half cup warm water with one teaspoon Epsom salts. It is given all half cup two times a day for three consecutive days. Best to give before eating as it will take up all the room in an empty crop. All half cup must be given. For a very small chicken, cut the amount of solution in half.
Epsom salts, magnesium sulfate neutralizes the yeast and then flushes it out of the entire system from crop to butt by gently stimulating the intestines to move it through the system. It is not hard on the chicken as it may first appear. The chickens I've treated have been energized by it, feeling better almost immediately. Fresh water should be given in between flushes as this is dehydrating. Feed as normal, but wait to administer until the crop is as empty as possible.
