Second, pay attention to the building area. The building area of each greenhouse should not be too large. It is suggested that each greenhouse should contain no more than 4000 animals (personal suggestion). If the capacity is too large, it will easily lead to unexpected events, and it is too late to regret. If it is 4,000 chickens, it is suggested that the building area be 250 square meters.
