Since Chicken is a halal bird which is eligible for Zabiha, can it be used as a sacrifice for Eid Al Adha? And what about fish which does not require a Zabiha?
The predominant opinion is that only the an'aam animals (grazing livestock, e.g. goats or cattle) are valid for udhiyah. Despite the fact that fish and poultry were known during the time of the prophet, it is not reported that he ever sacrificed such, or allowed his companions to do so, for Eid.
