Run area for grass to survive?

No, they will have that stripped/eaten bare in a week or two ... Maybe a 50' X 50' ... I plan on 100' X 100' for a dozen, and still let them out when we are around ...

ETA: What I mean by "let them out" is free range outside of the 100X100 when we can be outside with them ... Maybe an hour a day, plus more on a weekend ...

 

They also scratch and dig. This disrupts root health of the grass. I agree with RedBeard. Chickens can turn a rather large area to dust and dirt, given enough time.

 

I have a 100x100 area for 18 chickens, and over time they have stripped bare some sections, usually the areas where the grass was not thick and vulnerable to excessive scratching. You can also limit the amount of time they are out so the grass is not under constant attack from the chickens. Mine get out 2-3 hours each evening, and 8 hours a day on weekends. This has allowed 80% of the run to grow well, I have to mow it every 2 weeks or so. The other 20% is stripped clean and the chickens use it as their bath area. Luckily, they stripped the area immediately behind the garage, so it is not easily visible.

 

When growing up many moons ago

We had 24 hens and one rooster in a run 25'X50' ... After two years there was nothing growing there other than a established tree, and a few bushes 4'-5' tall ... That's 50 square feet per chicken ...

A 50'X50' run for six chickens is 416 square feet per chicken ...

Thomas's chickens noted above have 555 square feet per chicken, and they are not out all day long either ...

The bigger the run is, the more it's like free ranging, and they will need less store bought food, and will probably be happier too!

 

We have a 50' x50' run for 27 chickens, they are only 9 weeks old right now and they have already started the process of destroying the grass that was growing there for many years. Lol! It won't take them long.

 

If you want areas of your lawn to stay immaculate, then you'll have to bar chickens from that area (or at least reduce exposure.) That said, you can also set up feeding meshes on the ground for grass to grow through, but so that the birds can't scratch out the roots. Then at least some areas will stay green & can be trimmed.

The meshes are easy to build. Basically a wooden frame with a 1/4 inch wire mesh on top. Sun, rain, & poop goes down - grass grows up.

 

Where ever you put them-IN A CAGE --NO matter what the size THEY WILL scratch it BARE !!! But you can do plots with screen over them-

 

Another option is to create a paddock system or have a very large run that is subdivided into two or more areas. Let the chickens roam in one area, then rotate them to the next, letting the 1st area have a week or two to recover and regrow before letting the chickens back in.

 

AkChris that IS A GREAT IDEA !!!! (If I only had the room) I so wish we didn't live in the city
