Trying to get the girls to lay a little more by adding a light. First time trying, always thought they needed the break. But feed costs and 8 girls laying maybe 1 egg a day ain't cutting it. They are roosting at 4pm now! Before the light was added they were going to roost at dusk, which is around 5:30pm here right now. The light comes on by a timer at 3am and shuts off at 7am. I have read that it could take 4-6 weeks for the light to make a difference but this going to roost so early got me puzzled. No change in feed (DuMor 16% Layer Pellets), water and free range all day/locked in at night. Your thoughts and advice would be much appreciated! Thank you!
