Anybody can perform Agnihotra irrespective of age or status. If the head of the family performs Agnihotra, the ensuing benefits shall extend to all members of the family automatically. It would be better if during the performance, all other members of the family should be present and chant the 'mantras' along with the head of the family. If the head of the family is away or unwell, then the consort should perform Agnihotra. In the absence of both, any other member of the family or even the domestic servant can do it. However, nothing goes a miss even if Agnihotra is not performed on a day due to circumstantial pressure. Agnihotra always renders benefits, and nothing else but benefits for all.
