IMHO the first thing you should to is contact your state wildlife dept or game and fish dept. Not only to find out if you can but they may be some type of cost share program for the birds and they might know where you could get them from.
It would be interesting to see if you could get involved with a population restoration project. Been trying to see who I should get in contact with here in Illinois about getting involved with raising them. It looks like a while back they were flying birds from out of state for a hefty fee which seems silly.
