Pepper stock ìn chicken soup often has gluten in it. Flour is used as a thickener.
I have been combing the internet and I cannot find a single recipe for chicken -stock that includes flour. Good chicken stock should be clear or translucent, This is impossible if there is flour in the stock. Chicken stock contains a chicken carcase or other inedible parts of the chicken, with or without veg like onions and some herbs, simmered for a very long time and strained.
This clear(ish) stock is then incorporated into a chicken soup recipe, again these recipes rarely if ever include flour. They are thickend by liquidized vegetables and/or cream.
Bought readymade soup, whether in tins, powdered, or in a carton may contain flour, but the OP is asking about home made soup. I do not think chicken stock sold as that in a supermarket contains flour as it is usually clear or translucent.
I wish the OP would come back and explain more, perhaps give us her recipe.
