I have 2 left to hatch . I can see the beak on one but no movement on the other. Yes a second light is a good idea. Don't beat yourself Kym I've lost little ones when they have fallen out of the nest box from momma. My brooder is in the laundry and I prefer to use the red globe so that every time i pass by I can see at a glance that it's on. The cheaper ones tend to blow out so always keep a spare.
