I am on dialup and so did not wait around for their pics to load, but I did read their text description with dimensions.
it sounds like the enclosed (house) part is less than 2x2', and the whole shebang is only about 2.5 x 6'. How many chickens were you going to put in there? I would not personally put more than 2 in, unless they were going to free range most of the day and even then you couldn't put more than maybe 3-4 onto that roost space and for that they'd have to be real friendly with each other.
Honestly I think you could probably score a secondhand rabbit hutch for a whole lot less and be as well or better off.
But, maybe you've spent some months *looking* for used rabbit hutches and not found any, I don't know what your area is like. In which case, I guess if you want a teensy tiny coop it is cheaper than some.
Good luck, have fun,
Pat
