A while back DH scored me these great boxes from work! They are 4X4 and about 3 1/2 ft tall. I have three of them so far! They come apart like a puzzle I cut the holes for the windows, doors, and nest box Covered the windows with wire mesh Covered the floor with peel and stick tile Here is a side view so far And the view where the door (left) and nestbox (right) will be. I will be adding the door and nest box in the next day or two. The door will double as the ramp up into the coop. I am also working with ideas on angling something over the windows that will keep out the rain, I just havent decided what to use yet. I am using them for breeding coops. I will also add a roosting bar to the other ones, but this one is for my silkies, so I left it out. The best part is you can just unlatch one side and lift it off for easy cleaning.
