We have to take a short trip and I am worried about leaving the light on my 2 week old goslings. It should get down to about 60 outside. They are in a brooder inside my chicken coop. I'm afraid that the chickens are going to be freaking out because they are locked up and knock the light down or something and start a fire. It's just a 100w bulb- but still..... Will they be ok without the light for one night? There are 8 of them. Thanks!
