Question about windows: How can we make watertight windows without having custom "real" windows made? We made our coop with three small windows covered with hardware cloth and sliding plexiglass - just finished yesterday (*YEA* ! ! !). But then we realized that rain can seep in. DUH! What have you guys done for windows? Thank you, Parents of 4 Buff Orps who are 5 weeks old and rampaging the guest bathroom until we get the coop figured out.
