My baby chicks should be here the first week of Feb. I bought this brooder http://www.strombergschickens.com/images/brooders/SBR_L.jpg from Strombergs. The way it is set up the light bulb is exposed. Do I have to worry about the chicks getting burned? Should I construct a little cage around the bulb? This brooder is much smaller than I thought it would be, I am unsure if I will even be able to use it much more than a week and I will have to come up with something bigger. It is actually just a converted covered cat litter box from what I can tell.
