Just on Saturday i had a similar experience, crept into an area i saw a little WT buck and 2 does the evening prior, waited 45 mins before making a sound, little grunt - nothing. 20 mins later little bleat - nothing. 30 mins later rake some brush to sound like a pissed off buck and within 2 mins had a WT doe clearly in estrus come running in. Was a first for me as this has always brought in bucks for me.
