I know I don't NEED supplemental light but... I really want some eggs so I'm trying it out. My question is how much light in the coop is enough? My chickens all roost in the evening even with the extra light on. Hubby thought maybe they needed a brighter light but they are still roosting. Is the extra light supposed to keep them awake or does it just work internally without them being awake? It's only 6:30 PM here and dark as midnight so they are already roosting for the night. Thanks!
