Is it permissible for a person on whose behalf an animal was slaughtered (in Aqeeqah) to eat from the delayed Aqeeqah?

There is no objection to eating from the aqiqa (sacrificial animal for a newborn), whether the aqiqa was delayed or not, and whether one performed the aqiqa for himself or someone else performed it on his behalf. It is recommended for one who did not have an aqiqa performed for him in childhood to perform the aqiqa for himself after reaching adulthood.
