Is it permissible for my father

Q 1: I own two houses, the distance between them is nearly 15 km, and I want to offer a sacrifice. Should I offer an Ud-hiyah (sacrificial animal offered by non-pilgrims) at both houses? Or should I slaughter it at one house only? Knowing that I have already slaughtered it at one of the two houses, and I brought my family of my second house to witness the slaughtering.Should the bones of the Ud-hiyahs be broken after slaughtering?Should the horns be broken?

A: It is sufficient for you to offer only one Ud-hiyah for the two houses as long as you are the owner of both, but it will be better to slaughter two independent Ud-hiyahs for the two houses, and there is nothing wrong in breaking the bones and the horns of the Ud-hiyahs.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
