Here is a nice article on an alternative to heat lamps; http://eggcartonlabels.blogspot.com/search/label/EcoGlow%20brooder
Taking care of chicks is not hard, but a little time consuming. They have to have adequate heat and fresh food and water every day. They need to have a safe environment too. Good luck!
A note about food: it is a personal preference, but I do not use the medicated food. I use 18-20% protein grower/broiler crumbles. I find the medicated food makes it harder to get rid of coxi, if they get it.
I have used probably everything out there for brooders. I tried cardboard boxes, but they get yucky and can hold mold. So I stick with Rubbermaid type bins, dog x-pens, little fences, and then I made my stacking 3-tier brooder. But the only thing I don't like about it, is that the wood is hard to sanitize. But it is nice until they are about 3 weeks old. Then they go on the floor of my garage. Here are a few pics of set-ups I have used. My brooder is at the bottom. Here is a link to how we made it;
