Some people build a coop with either a wooden floor, or pour a cement slab. Due to the cost of having a wooden floor and the cost of pouring cement, I am going with a bare earth floor. Also, a bare earth floor is natural to the chickens. This is the way chickens have been raised for thousands of years. My option is to either build a pole barn, or build a leanto chicken coop. At the current time I am leaning towards a pole barn.
Issues that need to be addressed: Square footage, security, food, water, lighting and laying boxes.
Square Footage – Its recommended that each chicken have at least 3 square feet inside the coop. For example, 30 chickens multiplied by 3 square feet equals 90 square feet.
In another article we discussed how many chickens are needed for SHTF. In that article we talked about having as many as 60 – 80 laying hens. Lets go with a high number of 80 chickens. 80 X 3 = 240 square feet.
Keep in mind 3 square feet is a bare minimum. The more space chickens have, the better. When chickens are packed together, they get bored and will start fighting and pecking each other.
The pole barn I am looking at building provides 192 square feet, which is 12 feet wide and 16 feet long.
The local building supply stores sell metal roofing in 8 and 12 foot long sections. Two pieces 12 feet long will be enough to do one end. Four pieces 8 feet long will be enough to do one side. This way the metal does not have to be cut to size and there is no scrap material left over.
192 square feet divided by 3 = 64 chickens.
