I agree with Cascadedad. Except I find that hunting with my dog (Yllw Lab) to be 50% of the fun to see her work fields, willows, sloughs (when frozen) and then to chase down if needed a bird that still has legs and clipped.

It depends upon the time of day, the weather and other conditions like precipitation. Warm sunny days early in the season, we'll see birds out near edges of roads and fields picking grit and sunning themselves to dry their feathers.
Cold weather, with snow, we work heavier cover like frozen sloughs, brush. Mid day they are usually out feeding in picked grain fields and tough to hunt. If you know of fields where they are likely to rooster for the night sit in your vehicle so you can see the fields they are likely feeding in and the areas they'll roost in. Watch where they fly to the last couple hours or less of daylight then go walk the field or cover working into the wind. Their less likely to hear you before you're in range.
I'd still recommend doing what you can to get at least 1 good dog with a good nose between you. It'll make the whole experience that much richer. Good luck!
