Are you thinking of getting chicks this spring? If so, you are going to need a chicken brooder. This is the box where you keep the little chicks for the first few weeks until they are big enough to go outside into the coop. There are a million ways to make a brooder or repurpose something else for this purpose. Basically, you just need a decent sized space with a floor that can be filled with sawdust, walls to keep the chicks enclosed and a heating source.
