I don’t have enough yard space that’s shaded to do a big aviary so stacked cages for me I think. They make vinyl coated wire that I heard is good stuff but I’ve never used it.I think that sounds like a good plan! I have some good stacked/multi tiered cage videos if you’re interested haha but yeah I think the big wire is the problem but then now I’m hearing all wire might be bad? So idk cause I’ve seen a lot of those cage videos haha
