Thank you for the info and links. It helps a lot. Here’s what I’m thinking. What if I use 1/4” hardware cloth between all the rafters in the coop instead of solid blocking, then put up a facia board but leave soffits open? Keep in mind I will have a 24” overhang both front and back. It seems that would provide tons of constant ventilation. The facia boards would serve two purposes, blocking the majority of direct wind while not impeding ventilation and also keeping any blowing rain/snow from entering the coop. The back wall will be 6’ tall so I figure if the top roosting bar is no more than 4’-4.5’ off the floor that would provide the hens with enough clearance over their heads to avoid drafts. Thoughts?
Yes, that would work well.
But use 1/2" hardware cloth. 1/4" is made from thinner wire that is easier for predators to tear through.
