Add-On Backyard Coop
|$799/each||$99 Shipping*||SKU 135|
Buy if you already own one Backyard Coop and you want to make a Duplex.
We calculate hen population based on ~4 ft² per bird run space (free range by Gov’t standards) adequate roost bar space, egg box space, and quantity and number of feed and water units. You add extra space because you’re being extra generous on space, or you’re adding room for extra hens in an optional configuration.
Shipping Rate Notice: This accessory ships for free when purchased with a coop due to bulk rate shipping on packages. * Zone based per item rate calculated in cart starting from shown price.

A little more about how we count...
Combinations are based on (1) reasonable available roost space (2) egg box space and (3) ground impact. When we design a coop we target a minimum of 4 ft2 per averaged sized bird assuming them getting no free range time. This number is for ground impact reasons and assumes you have good drainage and the ground drys up between occasional rains.
The above numbers favor run space regardless of roost or egg box space. Run space is a very, very personal decision. Many coop makers certainly provide less than our 4 ft2 per bird (averaged sized) target for run space. Our chicken keeping experience says 4 ft2 per hen is an acceptable number for healthy averaged sized hens that are caged 100% of the time and for things not to get too smelly. If you have the space and the budget, adding run extensions is always a great thing. It can never hurt assuming the additional space is equally predator proof to your main coop.
Our numbers are next controlled by roost space. In hot weather hens spread out a little, and conversely, in cold weather they will cuddle up more. The numbers we use are for average sized hens in a broad range of temperatures. Hens are very communal and will often all gang up on one roost bar even if there are two. Some coops don't even provided roost bars. Ours do because it is the natural best way for your hens to sleep at night.
Egg box space is not a limiting factor in any of the above stated scenarios. Certainly chickens have personalities like people, and some hens are more picky and dominant about egg laying privacy, but in general chickens share a space together or just wait their turn for egg laying. Again, hens are very communal creatures.
Egg production ranges assume 5 eggs per week as a low and 6-7 as a high. Some areas of the country have longer off seasons for molting birds. Daylight hours, feed quality and age of hens also effect lay rates. And of course breeds. For example, Leghorns are laying machines compared to most other breeds and will regularly lay an egg every day. Some breeds may only lay 2-3 eggs per week and that is normal for that breed.
