Direct heat is a good thing...drop the pan. My birds get diffused in the mini with the steamer pan but doesn't even need that. Birds in my UDS is the same way...directly over the coals baby and perfect skin every time. Dark skin and never rubbery. Same temps as you ran also. Do some more experimenting.
