I will be putting 48 eggs in the incubator this weekend. Assuming I get a good hatch, what size brooder do I need to give them enough room? Heat won't be a problem here in Arkansas in May. I have never raised more than 12 at a time. I know these will need MUCH more room. Thanks in advance. I know I am planning ahead. I just want to get the brooder built and then start on a new coop.
