IMO, they fail the "If it looks like a dollhouse it's only suitable for toy chickens" test.
A large-fowl chicken needs at least 4 square feet (.37 square meters), per bird. Bantams are usually said to need half that. So, theoretically, 4 large-fowl birds would need at least 16 square feet (1.4 square meters). Thus, theoretically, 4 bantam Silkies would have to have at least 8 square feet (.7 square meters).
The dimensions of those coops *might* just BARELY make those numbers on floor space(my metric conversion skills are a little weak), assuming that you have the feed and water out in the run, but the general design is so bad....
There is essentially no ventilation. You need at least 2 square feet and it needs to be set up to create correct airflow. The existing vents on the first one, though tiny, are kind-of in the right place -- at the top -- but there is no roof overhang and no shelter for the vents so the rain would come right in, forcing you to close them and have no airflow at all.
The second one has as much square footage in the nests as in the coop proper -- a sure sign that the designer knew nothing about chickens' real needs.
Cleaning either would be a nightmare because the access doors are small and those pull-out drawers are notorious for warping, sticking, etc..
