A couple of my (few) customers have come to me, by word of mouth that I'm selling eggs, and asked, "They're brown eggs, right?"
I reply truthfully: Some of them are. I have a backyard flock of many different breeds which freely range on the acre property and they all lay different colored eggs. There is NO difference in taste or nutrition between any of the colors, that's just the egg shell color from the breed. You will get 3 different shades of brown from light tan to very dark brown, a couple of white eggs, and a couple of green eggs in each dozen.
"Green eggs??!?!?!" Yup. So when they get their first dozen, and I show them the opened carton before I take the money for it, everybody has been thrilled.
Very few people ask if the eggs are fertile; sometimes I offer the information, sometimes not. I will tell them I have a rooster and have hatched one of the green eggs.... and that pullet will also lay green eggs when she gets older.
