I know this is very basic information, but I have never done this before and have some questions about using a heat lamp. I was at the feed store yesterday buying some of the supplies I will need for the chicks I'm getting soon (only 4 days now!), and a man standing near the checkout counter saw that I was going to buy a 250 watt red infrared light. He started telling me that I didn't want that, that it was much stronger than I needed, and that it would start a fire if I was using a cardboard box (which is what I have been planning to start them out in). I hadn't read or heard anything like this anywhere, and so I didn't know what to think. I tried to ask him what he did suggest using, but he didn't really answer my question. (The lady checking me out didn't seem to really agree with what he was saying, but I don't think she wanted to disagree outright with him). So anyway, I thought I'd ask about heat lamps here and get some different opinions. What types of bulbs does everyone here use/recommend? Are there any safety issues with using cardboard boxes for brooders, or with using certain types of substrate/litter? Obviously I would be hanging the light an appropriate distance away so as to achieve the proper temperature within the brooder. I should add that I will only have about 4 chicks. Maybe the 250 watt light is overkill for only 4 chicks? If I used something like a 75 or 100 watt white light, does it make any difference what KIND of bulb I choose? And does it always have to have a reflector? Sorry if these are stupid questions, I just have no idea what I'm doing (although I'm trying to learn).
