Into every life a little rain must fall. I am not sure exactly what happened but maybe it was several things. I had a chicken fire.
I bought some new lump, Lazzari Mesquite. I loaded some into the egg on top of old lump. May have had too much lump. Plate setter legs up. Another possible problem was the drip pan was set directly on the plate setter, just before meat. Grid on top of that. Fire did not want to settle down to a "clean" burn. I waited a little more than an hour.
I put whole chickens on at 400° dome and everything was fine for a half hour. Then there seemed to be fire underneath and in the drip pan everytime I opened the lid. The chicken skin got black and smoky from the fire and not brown from the heat. I finally got the breast up to 165° and all the juices ran clear. I pulled in a hurry. It started to rain since we already had two days of sun. The birds did not look the least bit appetizing. They were barely edible and nobody complained but I was not particularly happy with the result.
I am a big boy and this is all on me, it is not the egg's fault. The egg didn't do anything wrong. I am keeping the egg. I would just as soon not to have it happen again.
