I realize that sounds like a pretty stupid question, when we want baits that "smell". But, I was using some old(I have frozen and defrosted them about six times and they are over a year old. Ya, I know, but I usually buy a bunch of tubs at the same time.) ones the other day, and I did not get a nible on them. When I switched to new chicken livers that still had a red color to 'em I started to get bites. Has anyone else had this problem?
