1. Do they make anything in a lower wattage then a 25 watt bulb? My homemade incubator is super small and even the 25 is getting it too hot. 2. I think I have a sinus cold...can my chicks get it? Can I infect the eggs? 3. Do I have to open the quitters? They are in the last week and I don't really want to look. Thanks!
