I purchased two of these since I have 8 chicks...I was able to put them together with the nesting boxes of opposite sides so that I could place them side by side...someone asked if you could connect them...there is a small gap between the two due to the roof extending over each side, however, with a little imigination they could be connected as long a they are put together as I did with one nesting box to the right of the door and the other to the left.
