I think $4.00 is a fine price, and would pay it for a female chick from culled hatchery stock. If your birds are well bred, then I would charge more. As the little guy I dont see the point in competing with the hatcheries, you have to turn a profit, or at least cover expenses.
I notice my birds seem to sell in streams, no one wants my chicks right now either, but everyone wanted them last month. So I'm just holding onto them, and will sell them later.
