New egger here! I got my first egg on fathers day weekend, its awesome so far we have cooked ribeyes, clams, ribs, burgers, grilled tomatoes, romaine lettuce, plank salmon, spathcock chicken, shrimp, meatloaf, sliced potatoes with onions and wings. everything was awesome!! the wings are the only thing that could have been better, maybe cooked a little longer. So now my first overnight cook I don't have a controller (yet) I put the 10.55 lb butt on at 4:30pm I was going for 250* dome was about 235* I did get it to hold 250* for about 5 hour before I went to bed, when I woke up at 4:30am the dome was 200* and internal was 165* so I opened the bottom vent and looked for a porker (don't have one) tapped on the grate with the ash tool and nothing, so I opened the top vent and blew some air in the bottom vent and now i'm back to 240* and holding. Is it normal to drop overnight or was my fire going out?
