Hi - I have 4, 4week old chicks. The brooder I have, is like a large rabbit cage, and I've had it in my shower for the last month. Chicks are doing great (although I think one of them, a SLW, is a roo.... argh). But, I'm thinking they are getting too big for the brooder - every time we come in to the bathroom, they are flying around and they just looked cramped. Should I change their brooder to a bigger cage? I guess this sounds like an obvious answer.... Thanks.
