I've looked over a lot of threads in this forum but I can't seem to find any that address similar projects, so I'll just describe what I've got in mind and hopefully some of you all will have opinions. I have a series of raised garden beds and would like to attach a chunnel to my coop so that my hens can travel around the perimeter of the garden and help keep weeds and bugs in check. Kind of a miniature chicken moat. However, the chunnel would have to cut across the gate into my backyard, so I would like to be able to move it or even put it away and store it without a lot of hassle. Storage space is also an issue. If I decide to put the chunnel up during the winter I need something that will fold down flat, hence the A-frame design. Has anyone seen or built an A-frame chicken tunnel that can be folded at the peak? I'm hoping for some pros and cons and any design tips you have to offer. I'll be building the frames out of pallet wood and covering them in chicken wire. I'm framing out the coop and run this week (I should be sleeping right now so that I can get up early and get to work) and it will have a special door for the chunnel opening, so keeping predators out should not be a huge issue. The main questions I have are (1) how to secure the sections of the chunnel to the ground so that they can be relocated without a huge ruckus, (2) how to secure the sections to one another, and (3) whether my "chunnel moat" needs to go all the way around the garden, i.e. connect to the main corridor coming from the coop. As for this last question, I need a way to get into my garden and the simplest solution seems to be building a chunnel that goes almost all the way around but not quite. I have never put chickens in a tunnel before and I don't know if they have sense enough to turn around and circle the moat or if they'll stand there until it gets dark or batter themselves senseless trying to jump across the "people door" to the other end of the chunnel. If that is the case (I kind of suspect it is) then any solutions to the people door problem would be super helpful.
