They don't think there's a difference. When my eggs are cheaper than what they can buy in the store, they are willing to eat better eggs fresh from the farm. But no amount of talk will convince them to pay more for my eggs than the price at the grocery. If you have MISrepresented brown eggs and charged a higher price, then the fault is yours. Consumers rule, right or wrong.
Some people think brown eggs are better, others just fancy the color.
I guess that would be true for backyard flocks too. Dr. Bruce, you are right. I wish my yard was bigger. I hope you post the location. I was only relaying other info I had seen elsewhere.
