Shad does rule, but mink works pretty well if you can find it. So do tuna carks. And I can't tell any difference between turkey and chicken. I used both today at Hammond and both produced fat crabs.
Some grocery stores along the coast will keep outdated poultry and meat to sell for bait. The IGA near Siletz Bay sold me a pile of turkey and a whole frozen goose for cheap once. That @$#%&$# goose was about the size and shape of a bowling ball and just as hard. And it sucks for bait. Won't do that again!
