Hmm...I'm not so sure how good of an idea it will be to just go turn your young dog loose on a bunch of wild (wily) birds?!!
The thing you're looking at wanting to avoid is for it to just get "birdy" and take OFF chasing these things (great fun!) and flushing them wild.
(Remember it's easier to train good habits in than to UNtrain bad habits out

)
I'm not trying to discourage you from wanting to take it, but you'd like to get a handle on the dog's handling first.
Ideally you're wanting to teach the dog to quarter, that means go back and forth, left and right out in front of you...AND to stay CLOSE!
So you either want to work with your dog back and forth, using hand signals and/or your whistle to teach it to turn.
And you want to do this all WITHOUT birds.
Ideally you'd like to have very good CONTROL of your dog, and this usually takes a while to get this trained in.
Often you have to use a long check cord (a horse training Lunge Line works good) to get this working initially.
My current little Lab is now just over 2-1/2 and she's picking this up pretty well, but then she likes to stay close and I've never had to use a line on her.
My 2nd Lab, who was an Upland Bird hunting fool, took a few years of hunting before I was able to whistle her to a stop once she was on a running Pheasant... She was really good, but if a few roosters started running out in front of her, hold on! She was locked on and there was no getting her back!
Anyway, I'd say just take it easy turning your young dog loose on a bunch of wild birds WITHOUT proper field work first. If things didn't work out the way you wanted, it could be a pretty frustrating experience for you.
But you say your dog is "trained"...so maybe you've already done this?
If so, have at it and enjoy your hunt!
