96sqft figures up to 4.5per with 21 birds, so yeah....but integration works best with extra space. Might want to add 8x8 and have a wire wall divider for integrations.Thinking of adding a 4x8 add on to my coop. That would make it 8x12.I have 9 chicks at the moment and have 6 more coming in July and 6 in October. Would that be big enough for them? The run is gonna be 15 wide 35 long, still playing with those measurements
