We currently have a 2x4 coop, so 8sqft of space, and 6 birds (5F/1M). I keep saying our new coop - we are going to try deep litter instead of wire floor - needs to be larger, more like 18-20sqft for up to 20 birds. He is insisting that each adult quail only needs 1/4 square foot, and we can put up to 30 birds in an 8sqft space. I *vehemently* disagree with him, and haven't found anything anywhere stating they can thrive with so little space. Everything I've seen says 1sqft per bird is best. Obviously they can have more space, but not less. He is saying that 1sqft is anecdotal and not scientifically proven, and they only need 0.25sqft per bird. Can anyone help me out? I am not going to let him put more than 1 bird per sqft, but I'm tired of arguing.
