Answer:

Sometimes hens become so fat that the posterior portion of the body almost drags the ground, which condition is commonly termed "bagging down behind."

The flesh becomes diseased and is red and inflamed. In chronic cases the roots of the feathers are affected and the plumage drops off, leaving the bird in a most unsightly condition.

When the trouble has not reached the incurable stage, the remedy is to feed sparingly, giving mostly green food and compelling the bird to scratch for all the grain given it.

In addition to this, apply vaseline daily to the exposed portion of the body.
