Why you NEED a sturdy, ventilated chicken coop

While I agree the second is better, the fencing is actually worse. The first one has 1/2 HC but is of course not a good coop. The second has chicken wire which predators can easily rip through. Better than the original, still not great.

Its nice, but like @aart said, you are missing some key details.

Sorry, but sorely lacking details, especially about ventilation.
"Sturdy" coop(pic from web) does not look to have the mentioned space requirements.
