That's why I made mine with a door! The design you showed says if you want to completely close it in, make some sort of hinge on the top section becasue the gaps at the top of the side panels are the access. (meaning you have to lean in to get the feed and water dishes. I have to do that with my duck pen, but it is only 3ft high and the entire top opens in 2 sections. If I dont want to lean, I use a bungee cord to snag the feeders and the side of the water tub!
When I have moved mine, I have caught them and stuck them in a cage, but that is because they are still little and there are a lot of them. Once they get older, they will be able to stay out of the way when I move it.
One design I looked at said to make the bottom frame with the front and back boards ON TOP of the side pieces, leaving a 4" gap, so that when you move the tractor, "fewer broilers will get run over, they will just pop out the back" Hmmmm.... I think that was meant for people who have several of them and hook them to the tractor to move them! I pull mine slowly, a foot or so at a time and I think they will be able to move out of the way once they get a bit bigger.
