How to set up a chicken coop
Purchase a suitable chicken coop for your flock.
You'll need to decide upon the size, security, run and price. The larger the flock, the larger the coop.

Pick your answer from:
+ The more expensive the coop the more secure and size. If your chickens aren't going to be free-range (let out to roam in the garden) then you need to purchase a coop with an attached run.
+ Coop space needs to be suitable for the number of chickens you have and how quickly and often you'll house your chickens. A common rule of thumb is that you should have about twenty chickens per square foot of space.
+ If you only provide chickens for a short time, they will lose healthy, quality muscle and become weaker. If you have a flock that is over five hundred, and you can make at least one chicken coop for them, you may want to supplement your coop with a storage system made specifically for smaller chickens.
+ A first-generation coop will provide much more spacious housing than a standard chicken coop. Chickens can be placed in twelve-foot rows, or sixteen-foot rows depending on your flock's size and the level of growth that you will be building.
The more expensive the coop the more secure and size. If your chickens aren't going to be free-range (let out to roam in the garden) then you need to purchase a coop with an attached run.
