Please choose the correct ending to complete the given sentence: Pets and Animals: [header] How to set up a chicken coop [title] Purchase a suitable chicken coop for your flock. [step] You'll need to decide upon the size, security, run and price. The larger the flock, the larger the coop.

Ending1: 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. Ending2: 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. Ending3: If you only provide chickens for a short time, they will lose healthy, quality muscle and become weaker. [substeps] 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. Ending4: A first-generation coop will provide much more spacious housing than a standard chicken coop. [substeps] 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.
