I just made my chicken 15 minutes ago, I opened the pack and covered it in a decent amount of oil, sprinkled my spice over it and rubbed it in, then turned everything over and rubbed it in again, cooked 3 of them and put 3 in the fridge for tomorrow so they can marinade and surprisingly it actually tasted good when I was done, so I think not properly rubbing the spices in + mixing oil and spices before putting it on the chicken was the issue

Also I saw Gordom Ramsey say you don't want to keep messing around with the food while it's cooking so I just left it alone only touching it to turn it, also said don't cut into it while it's cooking or it gets dry which is another issue I was having
