Thank you, i have a 2x4 with the 1.5" up so i will rotate it, since the pictures i added a sandbox for them and changed half the floor to 1.5" slats spaced 1/2" apart so they have varied surfaces to stand on
1/2x1" seems to thin, do you do it on the flat or 1/2" side up, also do you mean straw on the bottom, because straw hold moisture which breeds bacteria and respitory problems.
Thanks
