I just noticed this post as well. I've had a quail surrogator from WMT for two years and run a website with my adventures -
http://raisingwildquail.com. There are lots of tips & tricks there. waynej's notes are spot on although I'm in TX and it's a bit warmer down here. We're seeing "bumblebees" on the ground and I suspect they are from last year's releases. And yeah, they will travel a long way - I've seen mine as much as 2 miles away! Habitat management seems to make a difference in keeping them around. I'm actually video recording a couple of cycles this year with the hope of making a video that will help people - I have a survey
http://raisingwildquail.com/surrogator-survey/ and if you'll tell me the information you're looking for I'll make sure to include it in the video.
