Put all ingredients in the slow cooker and let simmer for 1 hour on high and 7 hours on low.
Then remove the chicken. Remove the skin and discard. Peel the meat off the bones. I freeze it in portions as a soup etc. Pass the broth through a sieve. If necessary, degrease after cooling and also freeze in portions for storage.
If you want to eat soup right away, you can use the onion pieces as an insert; I throw away the remaining solid parts, except for the chicken.
2 soup variations with the poultry stock:
Variation 1: with rice or glass noodles, some of the chicken, bean sprouts, spring onions, some lime juice, possibly a little more chili.
Variation 2: with julienne strips of carrots, spring onions, some of the chicken,
1 teaspoon of red curry paste, 1 can of coconut milk and a little lime juice.
