I had put up the hardware cloth through half of my run's roof but wasn't going to do the rest because I'm putting a roof on the whole run anyway. (The clear/tinted roof material so light can get in but rain will stay out). I'm using multiple patio/deck screws to put it in to make it secure. I haven't seen a raccoon since moving in but I'm really worried about them. I know they will grab through the cage if the opening is big enough but I was wondering do they (or can they) tear through a roof? Would any predators tear through the roof I will throw barbed wire up there if I have to do it. Someone stop me. Please. I'm already over budget haha. Also looking for other tips. Motion lights too? Nite guard? I'm lining the bottom with hardware cloth. Doing a sand floor on top. May put a few of the extra huge rock/slabs I have left over from the previous owner in the bottom too. I'm used to seeing more wildlife in my old neighborhood where I grew up (just moved into my first house!) but that may also be because we had less dogs around. The dogs we did have were small, indoors and quiet. Excluding my big dogs of course. In my new neighborhood, it seems that everyone has dogs that are outside or inside so that may be why I haven't seen any night critters yet. I've only seen tom cats. I'm of course lining the sides of run with hardware cloth but I'm lining that bottom two feet with an additional hardware cloth that is smaller so raccoons can't pull them through. I've read buff orps are not flighty and are heavier so they should feel comfortable with a lower roost so I figure doing a bottom layer of smaller gap wire would keep them from getting killed/harmed through the wire. 1) Can coons or another predator get in through the roof? 2) Would motion lights or Nite Guard would be a good measure to take as well? Btw our yard is completely fenced in but I'm being extra cautious for my new chickens. Also, nervous new chicken mom.
