We got chickens. Our neighbor had more than she needed, and offered some to us. Before they arrived though, we needed a place to put them. I had to sacrifice the mini-greenhouse.
I picked up some 2x4' OSB sheets from the discount scrap pile at Home Depot. Total cost was $2.
I made a small box out of the OSB and attached it to the frame of the mini-greenhouse.
The roof is hinged. I also added a divider.
Finally, I covered the thing with wire mesh screen. That should keep the critters out. (I hope.)
The chickens seem happy.
We do let them out for a good portion of the day. They tend to hide under the deck and don't do much wandering.
