Well, I don't have a big, elaborate aviary - I'm in college, living with my mom, so I've built all of my pens to be transportable, with the idea that when I get my own place, all I'll have to do is rent a BIG trailer, get a few strong guys to help me, and move all the duck pens with me! /img/smilies/smile.png
Here's my favorite design so far - it still needed to be painted and shingled in the picture, and you can see that I hadn't hinged the little triangular door on yet. At this point, I HAVE painted it, but I still haven't shingled it - I just have two tarps to throw over the top when it rains. It's 8' long by 6' wide overall, and around 4' tall at the peak. So far, I've built two of these: one houses 6 Call ducks, and one houses 6 Bantam Cochin chickens, and I'm working on another that will house 4 Runner ducks. /img/smilies/smile.png
