long extension cord run?

I want to build a small chicken coop that will be in the far back of my yard. I live in northern Ohio so I'm wondering what to do about the water freezing in the winter

There's a 12/2 run to my shed (about 50' from the panel), I'm wondering if I can run about 200-feet of extension cord from that shed to my coop over the winter to run a 125-watt water heater. At about an amp it seems like it would be ok? What do you think?

if it's temporary. Make sure the cord gauge is lower, like 12/2 cord, to compensate volt drop. if its multiple cords then wrap the connections in a bag and tape. And plug it into a gfci outlet.

But keep it temporary! Think about digging a trench and putting in a permanent line. Im sure there's a post on this site on how to do that.

A #16 cord 200' long with a 1 amp load will cause about 2 volts drop. This is perfectly acceptable for any type of load. A #12 cord will have a bit less than 1 volt of drop.
