Hello Tim, I love Omlet! It's a great coop, this is half my chicken yard. I own four Eglu Go's, two I recently added the "UP". The blue one is a classic not offred in the states anymore.
I have 13 birds and they are all very healthy and happy. They naturally split up each evening between 3 coops. One coop never really gets slept in (it's used as a nesting box).
My birds have a big enclosure with the coops and run inside. I keep the runs open, & close up at night. This model seems to work for my flock. Knock on wood I havent had any problems in 3.5 years.
You can clean the coops with water and sanitized completely. I like to take the coops apart and move it or clean it. I live in the mountains at 6,500ft. & I we get snow and cool temptures most of the year.
I would cosider this coop it's awesome. Wood coops can harbor mites and such...
