This is a cute little chicken coop—but not of heavy or substantial construction. The wood is very thin. So this morning when we woke up four of our pullets (not even full grown!) were running around outside the coop, because the bottom of the nesting boxes on one side split and fell to the ground, presumably taking some resting pullets with it! Now we will have to reconstruct the boxes, which is not what we should be doing after a couple months of use. The roof will also require extra waterproofing-it is just a thin layer of rubber mat-and one piece arrived damaged so that there is a hole in the roof on one side. Finally this is probably the right size for six hens total (not 12!). 3.5 hours assembly.
