Help! Need Advice on Chicken Coop

[TonisChickens]

Help! I am looking to build my first Chicken coop. I have a 10X7 Shed that I am using as the Coop. I am planning on getting about 25 - 30 chickens. How big should I make the yard? I want the height of the yard to be 48inchs.

I would STRONGLY suggest you make the run/yard tall enough to walk into.
You will need to get into it.
