I have 2 new coops I built, one for chickens and on for turkey. I got them home last Thursday and all went well. Some time between 8:30 pm and 7am when My wife got up the GFI outlet tripped and the heat in the coops went down to 60*. My wife said the ranger chicks were all fine but the Turkey were not. 3 were already dead 3 were weak. When I got home from work only 2 were alive and I did not think one of the remaining 2 would make it but luck was good and we still have 2 of the 6. I yanked out that GFI and put in a regular outlet. I would love to shoot the GFI with my .45ACP but I don't want to get the new birds upset. Any other way to keep chicks warm or anyone here of a battery powered back up light ( ie car battery)
