SANHA and rainbow chicken

As Salaamu Alaikum dear Mufti Saheb
I am proceeding for Hajj this year insha-Allah and will be visiting Jordan and Palestine as well.
I would like to know whether the chicken for consumption in these areas are halaal suitable or not?
Are there any restaurants / establishments in Saudi where the meat / chicken can be consumed?
What is the ruling on eating from these establishments were chicken may be coming from other countries?
