I could really use some advice here. This is my coop. It's about 4'x4' with the bit sticking out where the nesting box access is. The run in the pic is 3 feet wide by 8 feet long and 4 feet high. My son and I built it out of hardware cloth, zip ties, and PVC pipe. It's great but is awkward with the coop. The run has a panel door that swings up to open so it lays flush on the top of the run. In this pic it's open so we can push the run right up against the coop, so the chickens can go in and out during the day. There is a pulley door to the coop that you can kind of see is raised and on top of the run. So my main issues are: - when the run door is open and the run is pushed up against the coop, there is no protection from the chickens running under the coop or something getting in that way unless I put something there like a board (the lighter colored wood in the pic) - the run is longer than the grass area so it runs into the plant beds, which are lower than the grass so I have to put rocks, wood, bricks, etc. around to cover all the openings - this set up is great for the chickens to go in and out as they please, but I want to be able to move the pen to other areas of the yard - if I set up the pen in another area of the yard, I have to physically relocate each chicken from the coop to the pen, which going in is sort of fine, but at night it's a royal pain and one of the chickens always escapes and we have to chase her all around the yard I'm thinking we should build something that can attach to the coop, give a small area for the chickens to forage and such, and come out on their own, but also can have access to the mobile pen so I can load them in and then move the pen around. I'm not clear what this should look like or how to build it. Please advise! Thank you!
