We got these 2 IB boys last autumn at about 4 mos old. They were given to us and we were not really prepared so it was a chaotic few months getting a proper pen and shed built for them. For a long time, they were only comfortable with me in or around the pen. When the school year started up again, I started spending time in the pen getting them to eat treats closer and closer to my feet and then from a hand held dish and finally from my fingers. Now, they rush up cooing in anticipation. It's been so much fun for the whole family!
