Thanks for all the replies.
In talking to a few people I'm starting to think it was the spread.
The wind was gusting, changing from dead to maybe 10 mph, blowing from behind me. I had the dekes set in a "J", all facing into the wind. My dekes were about 10' feet apart. 6 of the dekes were on motion bases and I flagged until the geese were 100-200 yards away.
I was using the RNT Dirty Bird, a call I have had great luck with. I was trying to do minimal calling, maybe a few honks while they were coming in. Everytime the geese turned or flaired I was not calling. Once they were past me I gave come back calls and flagged, turning severl groups to have them flair off again.
Also, the dog blind was new and I hadn't mudded it yet, but I had completely coeverd it and my layout blind with grass and then corn stubble on top of the grass.
