Suz: Did you say you're leaving your light on over night? They need the hours of darkness for their hormone regulation, as do we. The goal would be to get them gradually up to 14 hours of light/day. Most folks start the light in the morning and let the girls go to bed with natural sunset. So, if it gets dark at 4:30 PM, you'd want your morning light to go on at 2:30 AM. Personally, I don't want my rooster to greet the day that early, so: My light goes on at 6:30 AM, off at 8:00 AM, on at 3:30 PM, off at 8:30 PM. The girls are always on the perch for the night before the light goes out. I'm now getting 9/15 eggs.
