I plan on smoking 2 whole 5# chickens in my Smoke Vault this week. I figued I would brine them using the Slaughterhouse brine since I have never brined before. I was thinking of smoking at 300-350 to 165 at breast. But was unsure if I should leave them whole or open them up from the back and lay them out? Should I leave my water pan empty?Should I rub EVOO to get crispy skin? And anything else I may need to know. Thanks
