G'Morning Experts ! As the daylight grows shorter and the days & nights chillier, our chickens get up on the sleeping roost early. They were hatched this past May and have not laid eggs yet. My wife has a light in there. To save cost (electricity here is quite expensive along with everything else) she has replaced the incandescent bulb in the coop, with an 'energy saver' CF bulb. Will CF be as effective, in prolonging the day a bit and encouraging them to start laying? A pro is that it costs a lot less. A con is that it doesn't make quite as much heat. Cheers, Rob in Vermont PS Speaking of expensive, food prices are skyrocketing. Eggs are up to $4/dozen here, if you can get them. The 'good ole boys' are selling off some of their toys; e.g. the past Summer's ATVs and skidoos. They have signed up for heating assistance.
