I think when they get use to a feeder , it’s like ringing the dinner bell for them when you fill them up . When I first started hunting a former players dad carried me to his family farm in Paint Rock Valley . He put me in a lock on high in a tree and preceded to put out 100 lbs of corn . He hadn’t got out of sight before deer came from everywhere! Before the feeding frenzy ended their were over 40 does and fawns under my tree . No shooter bucks but it was a crazy afternoon for sure !
