We have a question about predators and floating duck houses, with the main concern being owls at night. We are in the process of building a large floating duck house for 15 ducks (Pekins, Indian Runners) and it will be in the middle of a small channel of water surrounded by trees. The house will have 3 walls and a roof, with the 4th side open so they can easily get in and out. Do you think it would discourage, or perhaps encourage predators if we shined a small light on the house? Just trying to think of anything that might help. Thanks!
