i've actually left this as a reply in another thread, where i found all the answers i needed, sans one. here it is: our hens have stopped laying, we get 3 eggs a day & my 2 little girls eat 4 eggs a day..... so you can see our dilemma. i'd like to encourage a bit more laying, with a bit of light. i was thinking a low-voltage light bulb, like a florescent (those crazy spiral ones, you know the type). we have 11.2 hours between sunrise & set. if i were to use a simple 13w florescent- not sure what that converts to in light output vs. a conventional bulb- would that be sufficient? i thought i would let it run for 1/2 before sunset for 3 hours total. thanks!
