MMMMM! If the broth is very gelatinous when cool, then you have made an excellently cooked chicken stock! To keep it from turning into Jell-O, just add about a cup of water when you have removed all of the bits.
Now, here is a good way to do it, though chicken broth is best made in an open pot, cooked on the stove.
1/2 of a chicken cut up at the joints
1/4 of a small onion, chopped in half
tsp. salt
1/4 tsp. pepper
1/2 of a tsp. chopped celery
Put all in the crock pot, fill enough to cover with water and place on high for the first hour. Reduce to low and add water if needed. Simmer for 4 hours, of if you like to let it cook when you go to work, then do so. With a slotted spoon, remove all meat and vegetables and place the meat in a bowl for later use. To clarify the broth, pour through a colander or sieve. Return to pot and taste. If too ‘chickeny’ add water as needed to dilute it. It probably will be too ‘chickeny’ because crock pots return the steam to the fluid and tend to condense the flavor, which is why I choose not to use them for most broth’s.
Bring the broth to a second boil by putting the pot on high, with the lid off. Taste. If too watery, let condense through evaporation. If you need a bit more vegetable flavor, add one or two chunks of onion or celery and let cook, tasting every few minutes and when flavored just right, lift them out.
To skim, let cool and skim off the rising oils or pour into bowl, which will cool it faster, and skim with a big spoon. You can buy a grease separator at almost any department store for around $1.00, which makes it much easier.
When done, you should have an excellent broth for your consumption. If it jells, dilute it. Jelling means it is concentrated and is usually desirable. Freezing jelled broth gives you a frozen broth that can be scooped out with a spoon because it will not hard freeze!
