Built around the size of the largest cage pan TSC sells, 30x36 inches. No wire in the bottom, just the pan that will get sand. Half wood, half wire around the sides and a solid top. The lamp will get affixed inside the boxed portion. Access doors on each side. Can't wait for the babies to be big enough to try it out! The barn isn't heated so I'm weather watching for the move. They're designed to be stackable, up to 3 high. They're 2' tall. This way I can separate batches by breed. Used 1/4" hardware cloth for the wire. Have 2 done so far. Next we need to build the juvenile pens, for after they're feathered. I use large plastic bins for the first 2 weeks to get them started inside where I can keep a close eye on them.
