The fine mesh that comes with most screen cages will remove nails on chams. I think it depends on how heavy the chams are before it starts to trap them. The only reason to have mesh that size is to keep small food in. If you are into DIY projects you can use vinyl coated hardware cloth 1/4 x...
Depending on what exposure the porch gets you can house chans outside fairly easily. I would put an automated mister out there to make life easier, the bonus of being outside is drainage isn't usually an issue. Other than plants you can run bare branches to give the cham an un-shaded basking...
