Greetings, These are my first chickens (had guineas for years before this) and I'm trying to figure out the supplemental light for the coop. The Barred Rocks and Silver Laced Wyandottes are 19 weeks old and I just added a light to come on at 2AM. I've read several books, recommended on this forum, and searched on the forum threads, but can't quite figure out if there is an exact illumination requirement to help trigger the hens' laying. I'm using a compact fluorescent bulb the equivalent of 75 watts in a 10'x10' coop. The bulb is mounted in a reflective brooder lamp and hangs about 6' above the floor. Does this sound right? Thanks in advance for the help.
