I bought the 42" by 82' and I like it real well I just use it in the yard and move it around. I wanted a fenced off area to keep the flock out of the veggie garden. I didn't purchased the electric charger, the Orps and Brahmas have never made a move to get out of it and I only use it when I'm at home to keep an eye on them.
I don't plan on using it in the winter and snow anyway unless its a nice day.
