Mine are calmer with the red lights. If I turn on the white one they fly about and bump chest( the ? males of the group). I leave the red on at night for heat and add a white during the day high enough that they don't get the heat but sort of have daylight. The white goes off at night. I think they rest better that way.

I used the white light before, and am now using the red light. They do seem calmer with the red light. I do what crazyhen does--leave on an overhead light during the day, so they have a sense of "day", and have a red light on all the time. I used to think the red light was kind of weird and it bothered me, but they seem happy.
I used white with the chicks I got last summer, and didn't have any problems. This time I'm using a red bulb, and I really don't see a difference. The only thing I don't like about the red bulb is that I can't see the chicks poo to make sure it's normal (I'm an over protective, paranoid mama hen
I used red last year and white this year. So far I have not noticed a difference in behavior except that this years batch of chicks seem to 'talk' more than last years. That could be due to a difference in breed though.
