I currently sell mine for $2.00 a dozen, which is what they were going for at the 2 gas stations in town here where someone was selling theirs. I deliver eggs to the nurses and docs at the local clinic, right down the street from me, and they order any where from 9-11 dozen a week, so there is a waiting list going at all times. I guess it's a fair price for them when they have to wait. I am going to be adding 6 more hens to my flock next week (I hope) to try to keep up with my orders, and maybe have enough so that I can eat some, too!
Another consideration is that I do sell mixed sized cartons.
