I was thinking that's a mill problem, too. 3 lbs of extract in a 5 gallon patch works out to be about 1.024. did you look at your crush? I did a few batches where I had horrible efficiencies, and I realized that my mill was spaced out a bit too far, and most of my grain wasn't getting crushed. Once you mashed in, did you get it good and stirred up?
Also...I think I read everything here, but does your hydrometer read zero with plain old water?
