CFLs in coop . . . safe?

[frankenchick]

I know CFLs contain a small amount of mercury, so if they break it's a major mess, but are they safe for the coop? Mine would be a "daylight" 60-watt that would be mounted up near the ceiling of the coop. I know severe cold makes them take longer to brighten, but is there any other problem I should know about?

What about having one on a timer? Is that okay?

Well, we have one in a shed outside & "takes longer to brighten" doesn't even begin to describe it!
Sometimes it just stays gray... never really lights up. I wish it were a 'regular' light.
I wouldn't put one in a coop - seems too much hassle to me. With all the dust and feathers, I prefer a nice small 35 watt that I can cover with a cheap Mason jar.
