This thread is from 2009. The person that you replied to has not been on BYC since 2013.Could you send pictures of your setup with the light in the cookie tin, please. What I realized with my turkeys is that they cannot drink out of something shallow they need to almost put their whole head in the water apparently. I've been taking out water three times a day but if I could figure out something else I would. I have a battery pad heater under the chicken water I wonder if it would work in a metal pail?
