As we mention in our Guide, you need somewhere between 2 and 4 square feet per standard size chicken in order for them to live comfortable, healthy and happy lives. So, your coop needs the following amount of square feet: 11 Chickens: 22-44 square feet 12 Chickens: 24-48 square feet 13 Chickens: 26-52 square feet 14 Chickens: 28-56 square feet 15 Chickens: 30-60 square feet Most chicken coop dimensions are shown in inches, rather than feet, so in order to get the area of a chicken coop in feet, you are first going to need to divide the number of inches for each dimension by 12 before multiplying the length times the width to get a coop's square footage.   Unfortunately, not every chicken coop manufacturer is entirely accurate in stating the number of chickens it can hold (let's just give them the benefit of the doubt and say that they are really bad at math). So, please do your own calculations before deciding which coop is best for your flock of 10+ chickens.
