I'll let him have some fun for a couple weeks and then start working with him a bit, getting him used to birds.
Let him be a pup and have fun for more than a few weeks. What is the rush? At his age you don't "work" him. Let him chase and bust birds and generally raise hell and get fired up about the whole deal. He is a little young to be worked, even a bit.
You "work" on the basic commands with him and when the time comes for bird work he wiil be ready.
Nice looking dog, congrats and wish you and Rugar many fun years together.
He has some good blood in his veins, the only one that can .... it up is probably you. Go slow.
