Two Hens and their Eggs

Two hens met after a long absence and one said, "How are you Mrs. Leghorn? I trust your eggs are doing well."
"Quite well, thank you, Mrs. Rhode Island Red. They are selling for sixty-five cents a dozen."
"Indeed?" said Mrs. Red, with more than a little complacency.
"Mine sell at seventy cents a dozen."
"Is that so? Why is that, I wonder."
"I presume it is because mine are larger."
Mrs. Leghorn shrugged with elaborate unconcern. "Good luck to you, then. As for me, I have no intention of tearing up my gut for a lousy five cents extra a dozen."
