Are these baby chicks? The only time I've heard of supplemental light is during the winter. You need 14 or 15 hours of light for the hens to lay well after their first winter. Their very first winter most will lay fine without any supplemental light. After their first winter most will go into molt and stop laying. The supplemental light is to get them to start laying faster. However, I have never read anything about baby chicks only getting so much light. Are you using a heat lamp with a red light in it? It should be on 24 hours a day for the first several weeks for babies.
Maybe someone else knows this system you are planning on using. I'm just lost but then I've only had chickens for 4 years.
I have never used supplemental light. Of the pullets I got last spring, they started to lay at 19 weeks. During the winter the 9 pullets laid between 6-8 eggs a day without extra light. I probably won't give them extra light this coming winter as I've got ducklings coming soon. They should lay during the winter so we'll have plenty for us to eat.
