I got the bright idea of using some metal fencing poles that happened to be laying around in the yard as roosting poles for my chickens, but now that cooler weather is setting in I'm wondering if it is a bad idea. I know how cold metal can be compared to wood or PVC and even though I live in southern Louisiana and freezing weather is rare, I'm still wondering if I should swap them out for wood. The chickens don't seem to mind them now, but in a couple of months, I don't want to find frozen chicken feet on the poles. Thoughts?
