Saute celery and onion in butter until onion is transparent. Fold into bread cubes along with seasonings.
Combine eggs and ½ cup chicken broth. Fold into bread mixture, adding more chicken broth if needed. (Amount of chicken broth needed is determined by dryness of bread cubes.)
Use to stuff a 10-pound turkey, 2 roasting chickens, or bake separately in at 350° oven in a buttered casserole for about 1 hour to serve as a side dish.
