Welcome to the BYC Family!!
We love sharing stories and bouncing ideas off each other.
I have 16 Easter Egger hens that lay blue, green, and pink eggs but Easter Eggers don't lay every day, they lay every other or every three days.
I built my own coop instead of a prefab coop since prefab coops aren't accurate with how many chickens it can hold. Looking at the link 
@Pork Pie listed is a great start to determine how much coop and run space you need. 
Depending on where you live... if it is winter right now, you could plan and research all winter and start building in the spring. 
You will want to either have construction underway or done before getting the chicks or hens, because they grow fast!! I didn't even start my coop until I came home expectantly with some chicks... I had to get a move on building the coop, and after 3 weekends of work, it was done.
