In a large stock pot, add the chicken, onion, carrots, celery, rutabaga, turnips, parsnips, garlic, parsley, bay leaves, salt, and pepper.
Cover the ingredients with enough water to cover all the ingredients. Approximately 2 gallons of water.
Bring to a boil then lower the heat to simmer, cover and let cook for 3-5 hours.
Remove from heat and let cool. Pour the stock through a strainer to remove the solids.
If not using immediately, transfer to freezer safe containers for up to 6 months.
Notes
Special equipment: You will need a large 3-4 gallon stock pot to make all this chicken stock. It's a great kitchen tool to have on hand if you already don't have one!
