I too have looked at the Henspa, but decided it will not do for me. I now have the Eglu Cube; and think that it is a fanstastically designed product. I own a wooden coop (built by hubby and me) with chickens before, and cleaning a plastic coop is little easier.
I think you have to look at your farmland and backyard. Are you actually going to move your coop over fresh grass every 3 to 4 days or so? If you are to do that, determine first how flat/level your land is. If your land is LEVEL, and the coop will sit flush/flat on the ground, without any "holes" where predators can wedge into the coop, then either the henspa or Eglu Cube will work for you. On the other hand, if your land has slopes, and is slightly bumpy - hands down the Eglu Cube, since the run flexible, and one can peg down the run skirt so that it is safer against predators.
I have now set my Eglu Cube on a stationary site; and that makes cleaning the litter out, and taking care of the chickens very easy -- I just walk into the run, and shovel used litter onto a wheelbarrow. After that, I replace with fresh litter. One the other hand, if one were to set the Henspa on a stationary spot, cleaning the litter would be a royal pain in the rear. There is no side door except for a removable roof. In wintertime, are you going to move your coop to clean the litter?
The Henspa is very attractive, and looks great as an elegant part of the landscape behind the house. The Eglu Cube looks like a very very COOL playhouse for chickens.
My email questions to Henspa have also always been ignored. Maybe it is because I ask about predator questions. My interaction with the Omlet company that sells the Eglu is very satisfactory.
You decide, of course, on what your needs and wants are. I think both are good choices; and the Eglu Cube works for me.
Cheers!
