Put them out the day you hunt.
I used a McKenzie deer target (made it aDoe without the antlers attached) with doe-in-heat scent during the rut, a few times. We painted it up to make it a bit more realistic. White on belly, around tail and on ears and face. Glossy black on eyes and nose.
We drilled a large hole near the tail and inserted a 35mm film canister. Put a cotton ball in there and soaked it with the doe-in-heat scent. Snap the lid on the canister when not in use.
If you find a small field where you've observed bucks chasing does in the late afternoon, this is a good place to set up the decoy.
Bucks will approach a doe decoy from the rear but will approach a buck decoy head on. So, set up accordingly to get that angling away shot.
