Chicken Coop for 20 Chickens or More

If you already know that you need a chicken coop for 20 chickens, it doesn't make much sense to choose one of the ones listed in our chickens coops for 16-20 chickens category. You'll want to look at these larger coops. It will give you the flexibility to add a few more birds if you want to and your chickens will be happier with a little more room.

As we mention in our Chicken Coop Buyer's 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:

  • 20 Chickens: 40-80 square feet
  • 25 Chickens: 50-100 square feet
  • 30 Chickens: 60-120 square feet
  • 35 Chickens: 70-140 square feet
  • 40 Chickens: 80-160 square feet

Please be sure to visit the bottom of this page, after all of the product listings, for further information about the size of coops and the number of birds they can realistically accommodate.

Chicken Coop For 20+ Chickens - Doing the Math

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. For example, a 132" x 108" chicken coop is 11' x 9', or 99 square feet. Depending whether you use 2, 3 or 4 feet per bird, that size coop could comfortably house 25-49 standard size chickens.

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 20 or more chickens.

Also, be sure to factor in the amount of roost space a coop has in addition to its number of nest boxes and whether or not it also has a chicken run attached to it. All of those things can limit or expand the number of chickens a coop can accommodate.
