Today was a BIG day for me. After wanting chooks for years I ordered 16 Gold Star chicks to be picked up in 6 weeks. I am starting to build the walk-in coop from "Buiding Chicken Coops For Dummies" but I have 3 nice vinyl windows I picked up a while back and I'm going to get a proper door instead of making one. I'm planning the framing and want to get your ideas about the positives/negatives of including a nest box door (like in the plans I have). I'm imagining that it would be nice not to enter the coop every time to get eggs but I'm wondering if this could potentially be a weak point for drafts/insulation (in Minnesota). Also, do the gals try to escape every time you open the door to a walk-in? Are exterior nest box doors common in walk-ins? Basic questions I know but I figure now is the time to ask. Thanks!
