This past Saturday I smoked some chickens on a UDS. I kept reading about them, and loving to tinker with things I just had to build one. (I copied Bubba's design)The smoker worked really well and was it easy to control the temps. Using the smoker was one of the firsts. The other was using an aluminum pan under the chickens to catch all the grease. I didn't want to have all that stuff in the bottom of the smoker. Anyway, The smoke went ok, but as you can see from the picture, the bottom of the birds didn't get much smoke at all. I did have them sitting on a muffin pan to hold them up out of the mess, but I still had limited success as far as smoke. And my smoker was running between 250 & 275 for most of the cooking time.
