Is it safe to cook raw chicken with rice?

Yes you can put them in the same time. I’d suggest you brown the chicken first, or remove the skins before cooking, otherwise you get mushy skin.

Can you use a rice cooker to cook meat?

A great way of using less dishes and pans is to cook meat together with the rice in the rice cooker. Simply, add in the rice and the correct amount of water then place your seasoned meat on top. The pressure and steam created within the cooker should steam and thoroughly cook the meat as well as cook your rice.
