Alright, so I have an acre completely fenced, with 4ft chain link. As you can imagine, chickens soon started jumping fence, even with clipped wings. I have a dog run, it is approximately 8'x20'. It is just a fenced in area, with the 4ft chain link too. That is where I placed my coop. Everything was fine, until they started jumping the fence. My coop stands about 6-7 ft tall, maybe a little taller, so I cant just add a flat cover. I am down to one chicken, since all others have jumped and then been taken by the neighbors dogs. I want my chickens back!! So, how do I fix just the 8x20 run area? I love the size of the run, so I would love to keep that, but not if the girls are gonna keep going over. My only idea so far, is getting an already built dog kennel, and fixing that up to be safe for the chickens. Only since that has the height I need, and can easily add a cover. But they are so expensive, and I would lose to much footage for the sizes I can afford. Does anyone have any ideas on how to extend my already built runs height so I can easily add a cover? Or how to build a cover on the 4ft height, up and over my coop? Or any other ideas of building a new area, on a cheaper budget. BONUS QUESTION: Since I will no longer be free ranging on my whole acre, and only keeping them in a 8x20 area, or 10x10 at the minimum, how many chickens would that fit comfortably? Thanks for any and all help!! I need my chickens!!!
