For starters, the numbers in the house must be comfortable. This is why over-crowding should be out of the question. Mature broilers should occupy at least 2×2 feet per bird, while layers require 2×3 feet per bird. The spacing is also affected by the given temperature of the house. If the house is hot, then you give them more space in order to have enough air. If you can afford, you can even use fans to make it cooler.
