JD, often the larger ones are golden colored, and the younger ones are silver...is this what you're seeing ? As for "if" you have a problem...probably not, but it would help if you said your pond was 4 acres, and the relative weight of your bass was 1.10%
Certainly 100's of 7 inchers in a small pond are a problem, while a handful are probably fine. As a general rule, if your bass are plentiful and fat, be thankful. While shiners do eat eggs, they would have to be heavily populated to do some damage...those big bass guarding the nests are a blast to watch, you have to have a LOT to be concerned.
