Is it permissible to buy fertilized chicken eggs for the purpose of hatching, knowing that they are sold for consumption and at the same price?

It is permissible to sell fertilized eggs for eating or for hatching, because both are permissible benefits. It is valid to purchase eggs for hatching, even if they are from a bird whose meat is forbidden to eat, provided that the bird is one from which benefit is permissible. It is stated in "Kashshaf Al-Qina'" that it is permissible to sell the chick of a game bird and its egg for hatching, but it is not permissible to sell eggs for eating if they are not permissible. In the Fiqh Encyclopedia, it is stipulated for the sale of eggs that they must be existing, valuable, pure, beneficial, and deliverable. Thus, it is not permissible to sell rotten eggs or eggs inside a hen's belly. In summary, it is permissible to sell chicken eggs for eating and hatching, whether before or after fertilization.
