I have had my Pilgrims for about 6 weeks. I got 2 adult pairs. The man I got them from let them free-range 24/7. I kept them in their pen for the first 3 weeks and then opened the door of the pen. It took them about 6 hours to decided to go outside. They will go in by themselves now. My puppy chased them last weekend and thankfully they can at least fly more than a chicken, she was a few inches from one gander's tail. I do not clip their wings, they have only flown a few times and that was just to fly around a little. I can pretty much tell when they are going to fly now. One thing I have noticed is if they feel threatened by anything, they will head straight to their pen. The only bad thing would be if a dog or other predator chased them into it, then they would be cornered. They discovered our pond for the first time today. I was a little worried that we wouldn't be able to get them back out, but they came out on their own and took a nap in the grass. They are so peaceful to watch, and are my favorite birds of all so far. They are so graceful and gentle.
