Stock up on light bulbs for your chickens

I had a realization today when thinking about the regular light bulbs being outlawed soon. You can't use those other bulbs to help keep your chickens warm in the winter; they don't put out any heat! I only had to give my chickens heat for about a week last winter, but it was sure an easy way to keep them warm when it got down to zero. I've been stockpiling bulbs for use in the house, but I'm going to add some for my chickens!
