DAF DISCUSSIONS - BEITZAH 3

michael plaskow asked:

If a hen is shechted on yom tov we are allowed to eat any eggs found inside. Yet there is certainly hachana involved within the hen. If the hen would have laid this egg on yom tov it would be muktsa and a case of "Davar sheyaish lo matirin". So why not treat the former case (Eggs found in shechted hen) in the same way?

The Kollel replies:

Tosfos (2b DH Milsa) says that the completion done on the day before the eggs are laid is not considered a completion unless the eggs are actually laid on the following day. This answer is very cryptic, and can be explained in (at least) two ways.

One possibility is that the Yerushalmi says that a laid egg has a different taste to an egg found inside a Shechted bird. The Ran (1b DH umid'Parchinan) explains that this is because as long as the egg remains inside the mother it is attached to the mother and is part of her. The Hachanah which causes the egg to be Asur is the fact that it becomes ready to be a laid egg. If this never comes about, then the Hachanah has not achieved anything significant, and does not Asur the egg.

Another possibility is that Hachanah only causes an Isur if the Hachanah is so substantial that it caused the thing that the Hachanah was done to, to arrive in the hands of the recipient. Here, however, the egg would have arrived in the hands of the recipient even if the Hachanah had not taken place, therefore it does not cause the egg to be Asur.
