We just got our 6 month old Runners on Saturday. We have them in a "newbie" pen that's right out where the other ducks can mingle with them, but not get to them and bully them, yet. Yesterday we opened the "house" door in the morning and let them go out into their temporary pen area. Well it was obvious they REALLY wanted to be out with the rest of the flock, but I wouldn't let them. I didn't want them picked on yet. Well they had OTHER ideas. The fence around the temporary pen is about 3 feet high. They stayed in it for a few minutes quacking their heads off at the other ducks and then the drake CLIMBED up and over first the fence and the 3 hens followed. THEY CLIMBED OUT!!!!!! I couldn't believe it. We've had many ducks in that newbie pen and I have never had one, not even muscovy, climb over the fence. It went pretty well. The runner drake had to prove he was a drake, I guess, and he did all the picking. He got his butt kicked a couple of times, especially when he tried to pick on a female muscovy, but mostly they just followed behind the rest of the flock looking a little, well, pathetic. They were with Pekins at their old home, and seemed to want to get close to my pekins, but while the pekins didn't pick on them, they basically just ignored them. When it was time to go to bed, and the other ducks headed for their home, the runners followed and went right into their newbie house. They are in the newbie pen again today and I'm sitting by the window watching them and they don't look interested in climbing over. I guess we'll wait and see. Did you know Runners could climb like that? I sure didn't and it was too funny!!!
