9 DIY Chicken Coop Plans for Medium to Large Flocks

Posted by Daphne Cybele

Do you have a flock of chickens that are growing in size? If your chickens have outgrown their small coop or if you're thinking of bringing home a large flock of chickens, you'll need a quality chicken coop that's large enough to keep all of your chickens safe at night. While you can definitely buy a pre-made coop, you may be able to save some money by building your own coop.

Are you looking to build a DIY chicken coop for a dozen or more backyard chickens? Well, you're in luck because we've compiled nine medium chicken coop plans with complete material lists and step-by-step instructions so you can make the hen house of your dreams.

Large chicken coop or smaller coop?

If you have the time and funds, it's a good idea to start off with a coop that's slightly bigger than you need to let your chickens grow into it, rather than having a coop that is too small. With a large coop, you have the flexibility and space to add more chickens, to section off parts of the interior (with chicken wire partitions, for example) to separate breeds or broody hens and roosters, or even to create a brooder to separate out baby chicks from older chickens.

These chicken coop designs are designed to hold 12 or more chickens. If you are looking for smaller chicken coop designs, check out our post (most of the small plans are also free).

Chicken Coop Checklist

Remember, a really good, functional chicken coop for your backyard hens is made of non-toxic materials, is predator-proof (think hardware cloth instead of chicken wire), and is well ventilated for good airflow.

A well-planned chicken house also has easy access for cleaning and to collect fresh eggs. A good chicken coop also has the right amount of square feet per chicken of space, the right number of nest boxes, and enough roosting bar space for the number of chickens you have. Access doors will make it easier to clean the coop, and the coop will need a space for a waterer.

Nice touches to put on your wish list are an automatic chicken door, a spacious and predator-proofed outdoor chicken run, and the ability to be mobile (a.k.a a chicken tractor). Read our backyard chicken coop checklist to really make sure you cover it all.

Fresh Eggs Daily tells us, 

"My rule of thumb: Build your coop a lot bigger than you think you will need. You only have three hens now By this time next year you will have 10 ... or 20 ... or 45 ... and maybe a few ducks..... Trust me. I know! So build bigger than you need at the current time."

My own chicken coop is a portable chicken coop. I have a small backyard flock and needed a way to move my chickens easily throughout the property. Egg collection is very easy and cleaning takes minutes each day! For a small flock a mobile chicken tractor is another idea to consider. There are two nesting boxes which are more than enough for eight hens!

Good luck on your build and on raising chickens!
