Great product.  Super easy to assemble.  Kids and I did it in about 2 hours.  I would suggest buying trampoline stakes (~$15 for 6) as the the ones that come with the unit are not sufficient IMO.  My chickens love the extra room to run and just be a chicken.  Reason I gave 4 and not 5 stars is the door latch.  Plan on going to hardware store and getting a better 'gate' style latch.  The one that comes with the unit is difficult at best to use.  Not a huge deal but definitely worth mentioning.  Would definitely get another one if I end up with more chickens in the future.
