I made my second run yesterday with my MES 40. Beer can chicken. About a 7 to 8 lb bird put mustard and a generic rub on the thing. Shoved a can of beer up its rear end and put it in my pre heated MES 40 at 275. Took somewhere around 4 hours to hit 165. Used my amnps but for some reason I had a real hard time getting it to stay lit. My previous fatties the thing burned like a charm with hickory pellets although I went through them a little faster than I should have. This time Cherry pellets same amount of openings for air but had a rough time. Maybe from the can of beer? Maybe the different pellets? My Daughter Said take a picture of me with the chicken dad!
