I have 30 keets coming this week and I planned on pinioning them to keep them in the pasture. I've read some posts that make me think that even pinioned they may visit the neighbors over the 6 foot wooden privacy fence. 20 of the keets are normal guineas, and 10 are Jumbo. What do you think? Will they likely stay in my pasture? (BTW, I have pinioned before, and although it is not my favorite chore, I am capable.) Thanks!
