No it hasn't been mentioned that I know. Good point Ron thanks for sharing. And for those who don't know yes Teflon / Nonstick coatings give off TOXIC FUMESWARNING..... Do you use "rough service teflon coated light bulbs" in your coop from GE or Sylvania ??
teflon coated bulbs are Toxic to chickens. One lady in New Hampshire lost 19 out of 22 birds overnight when she used a 100watt bulb in her coop. I just read about it in" Healthy chicken bulletin" I get free in my email. you can also read about it in the Oct/Nov issue of Backyard Poultry. htttp://www.backyardpoultrymag.com/.
I haven't been on here much lately.. Maybe this has already been discussed
