Nearly all prebuilt coops are not worth buying; to small, too flimsy, pretty useless, especially for five or six standard birds.
A garden shed modified with added ventilation/ hardware cloth covered window openings makes more sense, or a hoop coop, made predator proof, or that wonderful Woods coop design.

I can testify for this. Have a homemade coop that is lasting 10 years so far without even having to redo the wire (I've never had an animal break through like a lot of people havw, I guess)
Paid 275$ for a coop that holds 1/5 as many birds, stretching it. Less than 6 months later, the window door is gone from one window and part of the door for the other one is gone. Less than a year later the wire starts popping off the frame. 2 years later I have several doors that only have one lock close so I have to keep my hen and babies in the house and not let them to the run until it's broad daylight
especially for creating holes. And adding more ventilation is always advised.
