Do you have it on a timer? Sounds like an easy addition compared to the other work we have cut out for us. It's going to be another spring full of heavy work.
Last spring we had to re-do the entire front yard because the county made us put our new drainfield out there. Then we built the duck house, pen and secondary run. This coming spring it's going to be fixing our problems with the duck enclosure and building two hoophouses. I'd like to go a year without heavy projects, but life just doesn't work that way...
We don't use a timer. When we go shut up the ducks, we turn it on. When we let them out and feed them, the light goes off. If the light goes out in the night, Man you should listen to the disgruntled quacking! They think the light is Mama, since I use brooder lights too!!!
