Question Detail:

 IS MECHIEN SLAUGHTER CHICKEN WHILE 2 OR 3 MUSLIM PERSON SAYING ALLAH AKBAR WHILE ALL DONE BY MECHINE ACCORDING TO ISLAMIC WAY TO SLAUGHTER CHICKEN IN FRONT OF THESE PERSON IS OK TO EAT?

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
In principle, it is compulsory to make the Zikr of Allah by saying “Bismillahi Allahu Akbar” or any other Zikr before slaughtering each and every chicken. If the slaughterer did not recite “Bismillah” before slaughtering any chicken, that chicken will be Haraam.
