Hello: I have my first guineas. 1-Pearl, 1 white and 2 lavender is what the breeder told me thy were. At the time, I just wanted them and knew nothing about a guinea. They were hatched in August 2010. I have keep the in a run 8ftx14f. Since i got them in September. They want out to free range my backyard, but I am afraid they will run away. I have a 6' fence ...should I clip their wings? I have 3 hens and one roo.
