I want to make a roos for my hoop coop. I think that I can take 2X4's and make a ladder to lean up against the back of the coop but I am having a hard time visualzing how to nail the cross boards on so that the birds have the 4" side up to stand on. I could do it easily and have teh 2" side up. Can anyone help me? I am not terribly wood working exoerienced and DH dosent know his way arounf the butt end of a hammer. Thanks
