Product description

Are you planning to upgrade your chicken-rearing hobby into a lucrative business? One large chicken coop accommodating more girls can be an excellent investment.

This 40 x 20 coop is designed to hold up to 60 adult chickens, which makes it an excellent option for large-scale eggs and fresh poultry production. Great attention to detail has been intertwined into every aspect to ensure it offers a safe and healthy home for your chickens.

The coop is set on a reinforced concrete floor and boasts a total of 800 square feet of floor space. It is complete with a comfortable 108 square feet of roosting and nesting space, organised with enough perches and nesting boxes for the flock. The nesting boxes are secured on the coop’s exterior and fitted with access doors to allow for easy egg harvesting. 

Proper ventilation is ensured, creating an eggcellent environment for your girls. None of your birds will suffer overheating. 

For its size, you can expect it to be easy to clean, and sure it is. It is spacious enough with broad access for adults to easily walk in, even when carrying supplies. 

Best of all, it is designed to be predator-proof, so there are minimal chances of losing your chickens to predators.
