I have a 100w heat emitter for my flock in the winter. I am wondering about using this with chicks. Some on here have reported that did not disrupt sleep schedules. According to Gail Damerow in Storey's Guide to Raising Chickens, chicks should be raised in decreasing daylight until point of lay. For a chick born after the summer solstice, this happens naturally. For a chick born earlier, artificial light would be needed? Last year's chicks were born in late June/July. Info? Opinions?
