Eggs sell somewhere around $.50-$1 each and occasionally $1.50 online depending what colors you have and other factors. Birds depend greatly if you are selling online and what your area is like. There is no way I would ever sell a button for $10 here. No one would pay that. I sell mine $3 each or $5 a pair until about 10weeks when they start laying eggs. Then I can sell them sexed and laying with their adult colors for $5 each and discount on multiple males. At those prices I sell all the fancy colors have just a few of the common colors leftover each hatch. Extra hens I'll keep if I have an open pen and just sell their eggs cheap online. The extra males unfortunately for them are not useful for anything but pet food. If I tried to sell any higher than that locally I'd be butchering half the ones I hatched.
