Hi K,
I think that the coop looks really good, and has some very nice features. 1. slide out poop tray, 2. pop door opens from outside, 3. coop opens up for access and cleaning and 4. attached run.
The seller has 99.4% positive feedback, you can check that feedback and see if most of it is coop or perhaps other items--possibly by what the buyers have said.
They seem very upfront about making sure that the buyer knows the size --- and having an attached run is such a great idea. Also the height would mean easy access to the nest box to gather eggs, and the slide out poop tray for dumping the poo in the compost.
It is wooden, and as such would mean that it would require yearly maintenance, inside and out. And I don't know the ease of construction/assembly etc. -- but there are a lot of good ideas incorporated in the design.
Infact, I'm so surprised that you didn't get tons of opinons to this, because most chicken keepers have very passionate ideas about coops.
From the size, I would guess that it could hold 2 standard sized chickens, and perhaps more if you get bantams. That said, I have an 'Eglu GO' and I have 3 standard sized chickens. They are giving me about 17-eggs per week right now, even in our awful heat...but one of my hens is a serious over-achiever, so she sKews the statistics, I'm sure. I consider thier productivity a sign they are pretty happy, and I think that the size I have is pretty equivalent to that coop. Mine is plastic, thus no yearly painting inside and out, and no wooden roosts with crevices where red-mites could get established. Also safe from predators which is pretty important to me.
Not sure about your climate, but I wonder how that roof would perform in drenching rain? The way it opens is cool for access I think, but could it be problematic for leak--or did I just look at it the wrong way?
I just helped a friend assemble the top-of-the-line Eglu Cube which costs a fortune, but is a pretty well engineered arrangement.
Perhaps you can ask the seller very specific questions, about the type of wood and thickness of wood, and the level of skill and tools that are needed to assemble it. You may also want to ask them what number of chickens the manufacturer recommends eventhough it is a controversial topic exactly how much space a chicken needs. Part of the chicken space equation is what breed of chickens you get, how docile the individuals are, how plentiful they feel their food and water is, how much time they have to spend inside versus in their run, and how much if any time they can free range or be in a chicken pen (play pen/portable pasture etc.).
Everyone will tell you it is too small, and you won't be able to keep all the chickens you will want, once you get immersed in chickens. But I think that everyone's needs are a little different, and it is like a car, what is best for one person isn't what another person should choose.
How many chickens you will eventually want will depend upon how many chickens you want to feed and care for, how many eggs you want and how much space for chickens you have.
If this coop fits your criteria, the number of chickens that you want, your budget and other chicken and lawn aesthetics, you haven't risked a fortune to get it.
Whatever you decide, get chickens, you will love having them. I can envision a very successful small back yard flock with this setup. Email me if you would like more info on Eglu and how easy they are to assemble.
good luck!
