How big a shed do 60 pigeons need to build?

60 pigeons need to build 6 sheds with a width of 3, a length of 15 and a height of 50 cm above the ground.

6 birds per square meter, 60 birds need 10 square meter. Tell you what, build six sheds to separate the young pigeons from the old ones, otherwise the young pigeons will be bullied and easily swim around in the sheds. Every pigeon will have its own place to rest in a multi-point habitat, so it is not easy to lose pigeons. Waterproofing should be done outside the shed. Use asbestos shingles on the roof, not colored steel. The whole terrace facing the sun.
