I do not have chicks yet but hopefully will later this spring. I am in my "research phase" right now and I haven't really been able to find anything with reguards to what size the brooder should be. Most things I've read so far just say a cardbord box is a suitable brooder, single use. And I've read that metal stock tanks make great multi-use brooders, but again, they didn't specify what size for how many chicks. I will have a maximum of 6 chicks, and I don't plan on breeding any time soon. I simply wont have the room for anything like that until after my fiance and I are married and have moved out of town*. Anyway, my question is, what size box/container should I use for 4-6 chicks? Also, is a glass tank, if large enough, a suitable brooder? What are the pros/cons? I have several tanks of various sizes in storage and I don't plan on using them for anything any time soon.
