That depends on your local market. I sell purebred chicks for more than that. And barnyard mix for less. If I raise them to the age of those pictures, I add $1/week. I would say they are worth much more than $5. Even for being cockerels.
Bielefelder seem to be increasingly popular- and will add size/mass and productivity to your flock. Not sure what you'd cross them over- but you could have some really nice dual purpose chicks starting with a Bielefelder rooster!
