I understand your frustration. You get so many different suggestions and recommendations. People will tell you this will work then somebody else says you are doomed if you do that. I feel for you.
Part of the problem is that we keep them in so many different conditions that different things work. We have different concerns. I brood out of doors so one of my major concerns is the temperature swings. How can I assure that they have a spot warm enough in the coldest temperatures and a spot cool enough in the warmest temperatures. You are brooding indoors so your concerns with heat is primarily to not have the entire brooder too warm.
Some people believe in magic numbers, no matter the different circumstances. You have to have a certain number of square feet per chick at a certain age no matter the circumstances. While I do believe room is important I'm not tied to any specific ratio or number. Even at a fairly young age cockerels need more room than pullets, on average. Some breeds are larger than others, even as chicks. Feeders and waterers take up a larger proportion of space in a small brooder as opposed to a larger brooder. Each chick occupies a certain square feet of their allocated space. That leaves the rest of their allocated space empty. The more chicks you have with the same allocation of square feet per chick the more free space they have. That means the allocated square feet per chick can be less in a larger brooder. Now a big one. Each chick has its own personality. Some can simply handle tight quarters better than other chicks.
I'll repeat myself. I think you have a good plan. Have a plan ready if they outgrow your brooder.
