Pre-heat the oven to 375°F and remove all but the bottom rack of the oven.
Transfer the chicken to the 375°F oven for 50 minutes.
Toss the apples and shallots with the melted butter and arrange the apples, shallots and remaining thyme sprigs around the roaster. Return the roaster to the oven and roast for another 40 minutes, until the chicken reaches the internal temperature of 165°F in the thickest part of the thigh and breast.
