I would like to start my (very first!) 4 chicks in a brooder that will be large enough for them until they are feathered out and coop ready. I am thinking of purchasing a rabbit cage (easy and cheap) that has 8 square feet of area. I plan to get 1 easter egger, 2 sex links, and 1 Welsumer chick, but if the purchased cage won't be large enough for them until they are coop ready, I will have a wooden brooder built to whatever size I need for the 4 chicks (sure to be more expensive, and sadly, I am not capable of building it myself). Our nighttime temps will probably be dropping into the 40's when I will be introducing them to their outdoor coop. Thanks for any advice.
