Rainbow chickens and commercial meat

As Salaamu Alaykum, Respected Mufti,
There still is much confusion on whether commercial meat is Halaal/ Haraam or Mahrooh, some Ulama say ‘Doubtful’ and some say ‘Abstain’, some say Halaal, others Haraam and some Makrooh,whilst SANHA say “eat with confidence”,what is your ruling in regards to meat produced under the current commercial conditions which include cruelty, stunning, scalder, unknown number dead from stunning, possible omission of Tasmiyah, Omission of Sunnah of Qiblah etc

Commercial meat in general?
Thanks,JAZAKALLH,WAS SALAAM
