Brooder size question

[CaloosaBirds]

I have generally hatched smaller batches of eggs (12-30) weekly rather than many eggs at once and have used bins for brooders. Because of restarting after a move, I have 60 eggs in my incubator now. What size brooder would fit all of these chicks? I need something new as I don't have my bin brooders anymore, and I would like it to be of a useful size for all the chicks at least until they are 3-4 weeks old. Thanks for any advice!

I think it's 6 per sq foot until 4 weeks. Then you need to start getting more room
