Crock pot Stuffing

1 cup butter
2 cup chopped celery
2 4oz cans sliced mushrooms-drained
2 cup chopped onion
1/4 cup parsley sprigs
12-13 cups slightly dry bread cubes (or 2 boxes Mrs. Cubby's in green box)
1 tsp poultry seasoning
2-2 1/2 cup turkey broth (you can add diced giblets but that seriously grosses me out)
2 well beaten eggs
1 tsp sage
1/2 tsp pepper
1/2 tsp marjoram
1 tsp salt
1 tsp dried thyme

Melt butter in skillet and saute onion, celery, parsley and mushrooms. Pour over bread cubes in large bowl. Add all seasonings and toss well. Put enough broth to moisten, add eggs and mix well. Pack lightly in crock pot. Cook on high for 45 minutes, then reduce to low for 4-8 hours.
