Hi - I'm a newbie with chickens. Working on my page right now to get pics up. Got my first 12 chicks ever on May 7, and I built a coop from scratch. My chickens are growing like crazy, and seem to be quite happy and cozy in the coop right now. I have a quick question. I've been running a heat lamp since I got them but now it's in the mid 80's and I think they're warm enough, even overnight. So I switched out the heat lamp for a compact fluroescent 15-watt bulb just for light. My question is, should I run the light all night long, or are the chickens OK being in the dark. Probably a silly question, so sorry for asking if it is. Thanks! Question 2 I need to post - I haven't built roosts yet. With 12 chickens, I think I need two rows of roosts. What spacing should I use for the distance between the top roost and the bottom roost?
