This is probably a silly question but here goes anyway. Does it matter where I put a second chicken door in the coop? I had to separate my flock into two groups because of fighting. Now one group uses the part of the coop I had been using for storage and uses the people door for access (the other group has a chicken door). I want to add a second chicken door for this half of the coop. Does it matter which wall I use? Is it better to keep it on the same side of the coop as the first door? The chicken doors will be open all day. Thanks!
