Wanda,
That's the way to do it! I've raised redfoots since 1996 and quit the reptile lights long ago. I toss in lots of varied food every day(if possible) and in the long NY winter they only recieve light from regular bulbs. Lots of garden kale(red russian) and dandelion greens all summer. Some edible weeds too.
My herd of 2.6(was much larger) produce tons of fertile eggs every year.
I think many people try too hard.
Just keep those babies WARM.
