Oh bummer. I'm going to be too late for this. I'm designing an A-frame quail coop/run for the quail I am hopefully going to hatch out in the coming 3 or 4 weeks. Ít's in the sketchup phase still. As usual I want things that cannot be combined because of the laws of physics. Building a 8x16x7' structure out of 2x4s and then wanting it to be portable is not really going to work, lol. So back to the drawing board and hopefully make some decisions soon. I think I'll go with 2x3's and wheels, lol.
