Spatchcock or split the chicken instead of the beer can method. I think the temp posted above was a typo, closer to 350 cooking temp is what I shoot for when cooking poultry. Point the dark meat closer to the heat, and only take temps in the breast, the dark meat will take care of its self being closer to the heat.
