Most smaller tractors don't have room for a nest box, but this one has one built right into the end ... and then the entire end comes off for cleaning. Nice! This style would actually work for those of us who are, shall we say, vertically challenged? Most tractors sturdy enough for me to trust with my chickens are too heavy for me to move easily. I simply lack the height to get the leverage needed to move them around. This one would lighten up quickly once that heavy end came off. I may have a chicken tractor, yet!
