Facebook Marketplace for your area. If you've got an idea of how many you get, you can estimate how many you can sell. My hens paid for their food and then some when I lived down in Suburbia. I've since moved out to the country, but since everyone out here seems to have their own hens, I make a once a week trip back to my old suburban area to sell eggs. Works out great. I get money to support my hen habit and I get to see my friends almost more than I saw them when I lived down the street!!!!
