I remember looking at those and thinking the coyotes and huge raccoons could knock it over or just tear it apart.When I decided to get birds moving here .. I bought prefabricated coop. There is outfit they mailed it.
I had 6 barred rock it could hold 2 it was shabby .. ended up using it as a hospital coop then gave it away later.
Telling them it could only hold like 2 big birds 3 little ones.
Not very secure either.
