One of my Silkies is recovering from an illness, and because of that and the weather, I've got her in a makeshift sickroom inside (in a bathroom). In the room, I added a lamp, that has two light sockets; a 23W CFL (gives 100W of light), and a 13W CFL (gives 60W of light). I do not want to increase egg production, but only want to mimic natural light as best I can. I added the lamp because the main light is connected to an exhaust fan, and I don't want to run the fan all day. My question is this: what bulb wattage is best for providing light while she's inside; 60, or 100W, or both?
