really its the hens you like the best. but for size of egg verses use of food and size of hen I can not think of anything better than the Golden comets. They are small, sweet natured, eat less but lay the largest brown eggs almost everyday. I however still like my big old girls the orpingtons. They lay less and have slightly smaller eggs but I just love them. Its a personal matter. for selling eggs, hands down the hybrids like the comets, and sexlinks. For staying power the orps.

PS, they say the heritage Delawares are great layers too. Speckled hen has some of the most beautiful ones I have seen.
