If there are deer in the area...and corn on the ground...the doe WILL be there.
Just make sure you hunt the wind right. The deer will come in from down wind and may be spooky, especially since it's a newly placed feeder.
Does anyone else feed in the area? Do deer know what a feeder is??
Around where I hunt, I hear feeders going off all around me at dusk and dawn...so placing a new feeder is kinda like ringing a dinner bell. Any doe within 200 yards of a feeder going off (no matter where it is or how long it's been there) sets off in a dead-sprint to make sure she's the first in line.
If feeders aren't common in your area, give the deer all week to get used to it (don't keep going back in to "check for sign").
