Hello, I have a 14 week old Phoenix hen. I know she can fly and I have just put her out in the coop with the other hens. I feel bad she can't go in the pen yet, but I am inexperienced in clipping wings. I have silkies and large breed chickens that I have not had to worry about. Any info on the procedure and when to repeat it would be appreciated! My kids would never forgive me if she flew away.
