there are several factors involved in feeder activity. the main factor has been established, you may be competeing with another food sorce. a trick i learned is apple flavored corn has sweeter taste as well as a scent you could follow. another factor could be pressure on feeder, if you hunt over the same feeder every year the deer will learn to become nocternal or just abbandon completely. you have to feed way before and well after the season you hunt or feed year round. the best advice i can give you without knowing all the factors is to feed 1 month before season starts and continue feeding well into winter. i always start with an apple flavored corn (which can be obtained thru most local feed stores) then slowly convert to regular corn or spend the extra $ and feed it thru out your feeding session.
