I have like 6 seed feeders out over the winter, less in summer when the hummingbird feeders come out. Primarily for my elderly moms amusement. There must be 10 different kinds of seed where I shop and I probably have 5 different kinds of seed. Most of the seed looks pretty much the same, how fussy are these birds about what they will or will not eat? Is there one or two "blends" that will make all of them happy? I am in the south end of Lake County.
