Welcome to BYC! Flying silkies, love it! If his flying starts to cause problem, you can always clip one of his wings so he can't get as much lift off. I've got one girl that has to keep clipped wings because she's figured out the grass is greener on the other side of the fence 
Thanks for joining!! Would love to see some pics of your flying fella!
