How Big of a Chicken Coop for 20 Chickens?

It was a bright, sunlit morning when I sat down with a coffee in hand, mapping out my plans for expanding my little brood of hens.

The ambition was clear: I wanted a flock of 20. But a lingering question had me sketching, erasing, and re-sketching: How big should the coop be to comfortably house them? After much research, consultation, and firsthand experience, I’ve learned that size indeed does matter when it comes to poultry homes.

To cut to the chase: For 20 chickens, you’ll ideally need a coop that offers at least 60-80 square feet of space. This ensures each chicken has a minimum of 3-4 square feet to themselves, allowing room for roosting, laying, and general movement.

Now, while the above gives you a straightforward answer, it’s worth diving deeper into the specifics, nuances, and my experiences, which might resonate with any budding poultry enthusiast:

1. Consider Chicken Breeds:

I began with a mix of Bantams and larger breeds. It’s essential to know that Bantams require slightly less space than their bigger counterparts.

Tailor your coop size based on the specific breeds you’re keeping.

2. Space Beyond Square Footage:

When I started planning, I mistakenly equated space with square footage. However, vertical space is equally crucial.

Ensure there’s enough height for perches, nesting boxes, and general headroom.

3. Movement & Behavior:

Chickens are sociable creatures. They need space to interact, play, and sometimes, escape a pecking neighbor.

A coop that’s too cramped can lead to stress, disease, and even aggressive behavior.

4. Cleaning & Maintenance:

The larger the coop, the more challenging it might be to clean. However, I found that a well-designed, adequately spaced coop is easier to maintain than a cramped one.

Proper space allows for better ventilation, reducing moisture and associated diseases.

5. Nesting Needs:

For my 20 chickens, I ensured there were at least 4-5 nesting boxes. Each box needs about 1 square foot. Having multiple boxes reduces territorial disputes during laying times.

6. Outdoor Access:

It’s not just about the coop. Access to an outdoor run can supplement space needs. I attached a run that provided an additional 10 square feet per chicken, ensuring they could stretch, forage, and dust-bathe.

7. Future Plans:

When I started, 20 was the magic number. But poultry-keeping can be addictive! Always plan for potential expansion. It’s easier to build bigger initially than to retrofit later.

8. Natural Elements:

Remember to account for windows, vents, and perhaps a skylight. These not only aid in ventilation and light but can also consume space. Incorporate them without compromising on the essential square footage.

In conclusion, while the guideline of 3-4 square feet per chicken is a good starting point, personal observations and understanding of your flock’s needs will guide the final design.

Through my journey, I’ve learned that a happy chicken is a productive one. And happiness, often, starts with a spacious, comfortable coop.

So, grab those blueprints, factor in these insights, and embark on building a dream home for your feathery friends!
