G.T.
Ive never baked chicken from a frozen state. I'd thaw it first by putting the package in the sink with cold water, it should thaw in about an hour. I'd go to a cooking website like allrecipes.com or something to find a recipe for baking in order to get your time and temp right. My guess would be 325 for about an hour tho if thawed..... it really depends on what exactly you are doing with the chicken.
