I have 3 americaunas that are 4/5 weeks mostly feathered out and 3 wellsummers that are 4 weeks almost feathered out, I accidently broke the red light and only have a white light.......can I leave them with no light. The white light seems much harsher than the red one, Im afraid they might start picking at the littler chicks?????????? Thanks for your input...Bird Lady
