Second law of thermo question about chicken egg...?
The frying of a hen's egg is a spontaneous reaction and has a negative Gibbs energy change. The process can be reversed by feeding the fried egg to a hen and waiting for it to lay another egg. Does this constitute a violation of the second law?
The second law states that the total entropy in an isolated system can never decrease over time...it seems then that this process would violate the second law...how can that be?

The chicken who ate the egg is no kind of isolated system. It has all sorts of energy coming and going besides the egg of interest.

No, in fact if you didn't feed the hen an egg so long as you were still feeding it something, it would still likely lay another egg. Therefore a hen laying an egg isn't related to reducing the entropy of frying an egg.
