Hello, first thanks everyone for all the useful information on the site. I am looking to start raising some chickens with a friend. We are looking to get between 40 to 50 chickens. Based on the information I have read I think we will get a mix of Plymouth White Rock and Buff Orpington. We will probably butcher 2/3 and raise the rest for eggs. So, my question is, how large does a brooder need to be to house 40 to 50.chicks? Plan on keeping this in my garage with lights for heat until they are ready to be moved outside. Is there a good number to calculate space for brooders? Thanks for your help in advance.
