Hi, I've read that the brooder itself should be kept 90-100 the first day for the baby chicks. But how about the room the brooder is in? Last year we kept our chicks in our basement, which is heated. This year, because we now have an indoor cat, we're keeping them in a little outbuilding that does have floorboard heaters. It's been pretty warm here (northern IL). I'm just wondering how warm the room needs to be. Can windows be left open if it's warm (high 70s, 80s)?
