Some of the best ideas and designs for building coops and runs are right here on the BYC site. There are litterally hundreds of actual coops with pictures of the entire process from planning to completion. If someone on this site wanted any ideas for a coop and run I could not think of a better place to go then right here and it is for free. Having said that I am amazed at the amount of people who start their coop and run design and one look at it shows that they totally ignored almost all of the advise given here. So many coops and runs are disasters waiting to happen as far as the ease in which predators can get at their flock. Then I am amazed when I read in the Predator section how a flock was killed off and the owners are completely at a loss as to why it happened. It happens mainly because their coop and run was deficient in regards to protection from predators.
