This is NOT a heavy duty coop and one should NOT expect that. But the instructions were very good and helpful. We put it together in three hours and it was quite easy. I love all the extra doors as it will be much easier to use than my previous coop. Also I was especially pleased with the two ventilation openings on the coop. It is quite a nice little coop and should serve me for many years to come. I also purchased pressure treated 2 x 4s and secured the coop to them. This makes the coop sturdier and will also prevent the bottom from getting dry rot if the ground gets wet. I am incredibly happy with this purchase!
