Given their propensity to quote mine and spin, I wonder what they left out of the story.
"Now one year later their small flock had increased to more than 60 chickens".
How many chickens were they left with after the 19 died? They could have been left with 59 chickens - we just don't know.
Did the chickens reproduce as we are being led to believe, or did they have to buy some more - we just don't know.
As usual, all unverifiable.
