I don't run power to my waterers, but back when I brooded outside I did run a cord to the momma heating pad in the brooder....For those that run power to their waterers in their run, how do you run your cord into the pen? Do you cut the hardware cloth? Looking for better ideas than what I have.
Outside the hoop coop/run:
I overlapped the HWC on this portion of the apron..
Inside the hoop coop/run:
The ground wasn't level. I used a couple broken fire bricks to fill in the gap AND protect the cord from damage. Then I attached a scrap piece of HWC over the opening.
When I was no longer using the brooder I coiled the outside portion of the extension cord (coop to outlet), placed it inside a failed waterer bucket project, then cut a notch at the rim for the cord that was still underneath the apron. I put on the lid and left it. The cord is protected from the elements inside the waterer.
The apron is grown over, but I can still access the cord if I need to.
