I need HONEST opinions. I am NOT a carpenter. I build stuff for fun and stress relief (even though they tire me to death). School is almost out and that means COOP TIME. I am wanting to have 12+ chickens. I wanted to build one, but found this. It's $299 and is pretty good. I figured we could cut the pop door out on the side, A vent on the back (probably 1'x5') and then a window on the side of popdoor. I'M NOT SURE THOUGH. I need to know what you guys think. http://www.homedepot.com/webapp/wcs...roductId=100211354&N=10000003+524467+10282013
