Hello could someone please advise me on how to cook a chicken?

[jonny]

I have purchased a extra tasty chicken, weight/kg 1.370, cost £4.18 from asda and the instructions to cook are unreadable. I have a fan assisted oven and haven't got a clue how long i should put it in for or what temperature i should set the oven to. The chicken is not frozen. Does anyone know the temp and time i should set for it. Thanks in advance
