I have only one extension cord to the de-icer as well. I tried some solar fairy lights, which I already had, but we don't have enough sun to run them on cloudy days at all.
Then I found some battery-powered (3 AAs) white LED Christmas lights at Home depot $6 each string, so I cbought 5 strings, and that has worked quite well.
If your coop is smaller and light inside you should only need 2 strands to make it bright enough to see. I left one strand on continuously 24/7 and it was 2 weeks before the batteries died.
I use rechargeable batteries in it.
The bonus is that from the light they get under 5 strands of these light run from 4 to 9 pm, they lay eggs in the winter as well.
If you can't find these lights in a store, I'm sure you could find some online. The brand listed on the package was "Home Accents".
Good luck
