This has been a very interesting read. I have been trying to figure out a good isolation coop for my broodies coming next spring and I own a bottomless, hinged top 'coop' that is ideally sized for a hen to be able to walk about and do her thing while sitting so I think I will use this on bare ground in the enclosure (has mesh buried 6 inches below the decomposed granite base) so she can build to suit, her own nest! Thank you for taking the time to write this article!
I would like to introduce a similar system that I could use in a coop.
