Large Chicken Coops | Backyard Chicken Coops For Sale

Large Backyard Chicken Coops

Chicken keeping is no longer a simple flock of hens foraging in the lawn or garden… calico-clad grandmothers in aprons tossing a handful of corn... rosy-cheeked children gathering eggs as part of their daily chores... fussy flocks scratching, squawking, or fretting angrily as the family dog paces nearby.

Modern life has made us all at least somewhat familiar with the migration of the humble backyard flock to ‘factory farms’ and mega food processing plants.

However, times are changing and there is growing public concern about where our food comes from, how it is handled and what is added before we consume it. The issue of animal welfare is also getting attention and raising awareness. People are increasingly interested in adopting a healthier lifestyle and that includes reestablishing backyard poultry in significant numbers.

Create Your Dream Coop

Exactly ‘who’ are the folks eagerly welcoming sweet baby chicks and tenderly nurturing them under a heat lamp in a box in the garage for weeks before resettling them into their very own backyard chicken coop?

Those buying chicken coops and their reasons for doing so can be as numerous and varied as there are breeds of domestic chickens! However, at Horizon Structures, we find the people who buy our larger chicken coops fall into a few broad categories…

Probably the biggest group of people buying large chicken coops are those who are truly concerned about the food supply. They want a measure of control over what they feed themselves and their families.

Large, pre-built chicken coops allow people to feed their families fresh, wholesome eggs from chickens whose environment and diet is monitored and regulated. Raising your own birds also ensures meat that is free from antibiotics or other chemicals and processed in a way that is 100% under your control from beginning to end.


Upgrade Any Shed to a Chicken Coop


A person who buys a large chicken coop will very likely have more eggs and/or meat birds than their immediate family can consume. A large walk-in chicken coop affords the opportunity to sell or donate the surplus providing an extra source of income or a way to make a positive impact on one’s community. The size of the flock housed in a bigger coop pays ‘dividends’ that can have educational and charitable benefits in addition to being economically profitable. For this reason, churches, organizations, and schools may also buy oversized chicken coops.

Over the years, buyers of our larger prebuilt coops have also included bird lovers or hobbyists who are interested in chickens for purely aesthetic reasons. People who keep chickens to promote rare breeds or produce show birds have found Horizon’s larger sized, custom chicken coops perfectly adaptable for meeting the special needs of their breeding stock. Creative custom layouts provide space inside the coop for working with the birds, separating roosters and hens, preparing for events, and caring for and raising delicate chicks.
