My son and I bought this for a brooder house .
 We have 57 babies that can not be mixed in with the hens yet. 
They will have plenty of room till they can move in to the hen house. 
 It was easy to put together and very sturdy. No tools required. 
Very happy with this house. 
It works great for the baby chicks but is a little small for 12 full size chickens. 
We did not use the roost bars or put in the dividers for the nest boxes. 
 it would be better if the roof was hinged for easy cleaning. 
Over all it is a great house and will withstand the weather.
