Perry's Index to the Aesopica
Fables exist in many versions; here is one version in English:
THE HEN AND THE EGGS
A hen came across the eggs of a snake and devoted herself to them, settling
atop the eggs and brooding on them. A swallow saw what the hen was doing and
said, 'O you stupid, senseless creature! They will destroy you first of all
and then destroy everyone around you!'
The fable shows that we should never put our trust in a wicked man, even
if he seems to be completely innocuous.
