In a crockpot add the chicken stock, creamed corn, frozen corn, onion, celery, salt and pepper (to taste). Give it a good stir to combine.
Add the chicken breasts and cook soup on low for 3-4 hours until chicken is cooked through but not falling apart.
Remove chicken and dice into bite size pieces; return to crockpot and cook on low for another 30-45 minutes, until chicken is tender.
Add chopped hard-boiled eggs and let heat about 5 minutes.
Serve over egg noodles, if desired.
