is putting that purple stuff on it good enough? Our do I need to do something else?
A red light heat bulb would be much better in this situation instead of a white light. But other poster is right, those red spots on their backs are just an invitation to the other chicks I was in a feed store once looking at their little chicks and one of them was getting it's little wing ate off by all the other chicks. I told the guy behind the counter, but he didn't seem the least concerned about it. You do need more space and maybe hang a little shiny bell or something in there to take their attention off the others. If they don't stop, you may need to separate them for a little while.
