Pour chicken broth into a large pot
Add the vegetables and seasonings and allow to simmer for about 10 minutes
Add the cooked chicken
Combine water, milk and flour in a jar, put the lid on and shake well
Add to simmering pot, stirring constantly
Pour into a lightly greased crockpot
Spread evenly and set aside while you make the sourdough biscuit topping.
To make the biscuits:
Add cold butter and flour to a bowl
Use a pastry cutter to combine. Once you have little pea sized clumps, add the sourdough discard, milk, maple syrup, salt, baking soda and baking powder
Mix with hands or spoon until mixture comes together
You can now either grease or flour a flat surface and roll and cut the dough, but I just took small handfuls, rolled them into a ball and flattened them in my hands
Place the biscuits on top of the chicken mixture in the crockpot
Put lid on crockpot and cook on high for 3-4 hours or on low for 6-8. Since the chicken mixture is cooked already and only the biscuit topping needs to bake, don't cook this too long! After several hours you can slant the lid a little bit to allow some of the liquid to escape.
