Keystone, what are the dimentions on your coop....?

Hi, I'm new here and in the field of poultry. My first broiler chickens arrived not a long time ago, so I tried to find as much info as I coul. Maybe you lready know this but may be not I found out that one of the main things to do is to make a chicken coop as big and free as possibe. As an example I found this coop that will allow to keep from 8 to 10 chickens. It looks amaizing! It doesn't even looks like a coop. Also, it's better to add stability to a feeder to prevent problems or even it's better to use hanging plastic feeders. For example, I foung this buying guide for chicken feeders and wanted to get something like the third one there but people on another forum had told me that it will be very small. So I've decided to buy something plastic like the first one from the guide and later to build my own feeder. As for the food, they will need special chicken food, which is already balanced with all the vitamins and minerals they need. This is what I found out so far. :-D Do you guys agree with it?
And here are some pics of what I have so far and what I'm planning to build

Oh, thanks! Haven't thought about it.

Broilers are typically 7-9 weeks to butcher, if you feed them the right food. Giving them a lot of area to run in will slow their weight gain, as they can get more exercise.

Studies in the 50s and 60s figured out that 1.25 square feet per bird was the best for meat development, for broilers.

Broilers are a completely different game than egg birds. Broilers will eat themselves to death if you freely offer food.
