well you can run a feeder all yr if you like
but to help a deer out winter is when a feeder is best for them , as thats the ahardest time of yr to find food for them
now thiongs are greening up, its gets easier here on out!
but has to be kept going all winter to really help at all
have to ask yourself what are you wnating to do with a feeder?? and then go from there!
as for a TR , well, I found that placing corn on it at first helps deer find it sooner
but not needed it the deer wnat it, they can smell them too as is!
minerals I think are more importany now till say sept, than any other time of teh yr so put them out now if you can!
