My red heat lamp bulb finally blew. I didn't have another so am using a regular household 100watt bulb. It seems to be working for the time being, but I have a question. It is much brighter than the red bulb and the chicks seem much more active (although this could be that they are just getting older). Should I turn it off for a short period every day, maybe even several times daily? Or just leave it alone. Just wondering if anyone had ever used a regular bulb before and what they did. They are almost 2 weeks old.
