Looking for best chicken breed that won't jump fenced

Ducks shouldn't jump a fence and Khaki Campbells are excellent layers. That said, you might want to go with a heavier chicken which doesn't fly as well as a lighter one. But they won't lay as many eggs either.
Chickens seem to love heading for the woods. They don't believe me when I tell them about the foxes living there. But two other things you can do is keep their wings clipped (Clip back the first four or five feathers on each wing just like you would a parrot. I know some people say clip one wing only. If you have predators you might not want to do this.
Most birds go over a fence by flying to the top then dropping down on the other side. If you string a wire three to six inches above the top bar where they usually land, that should stop their going over.

 

Greetings from Kansas, autumnoak, and ! Pleased you joined our community! I think the larger bodied breeds just naturally have less of a tendency toward flight. I know my Leghorns, Anconas, and Hamburgs are ALWAYS out. Certain of mine never seem to fly out - Orps, Naked Necks, Marans, and sex-links. Any way you can cover the run to keep them in? You can also trim the flight feathers on one wing. Hope you find a suitable breed. Best wishes and thanks for joining BYC!

 

You can also clip the wings of any chicken.

 

I am glad you joined us! I agree with @redsoxs , heavier breeds are the best choice! My Leghorns can fly pretty high, and I don't want to clip their wings so I just let them free range. I enjoyed reading this about gentle breeds:

Hope it'll help you!

G’Day from down under autumnoak Welcome!

Sorry, having 5 x spoiled bantams who fly like bricks and are in no hurry to leave their garden, I am not able to help with your query. I would definitely recommend anything similar to my gals but as you want egg layers not freeloaders I will just wish you all the best.

I do not know how much fencing you have but I did see this cool device which stops cats from stopping at the top of the fence before dropping down the other side, it might work with chickens

I hope you enjoy being a BYC member. There are lots of friendly and very helpful folks here so not only is it overflowing with useful information it is also a great place to make friends and have some fun.

If you would like to share pictures and stories of your flock, you have come to the right place. BYC’ers never tire of these and do not back away slowly or commence eye rolling when the photo album or home videos come out
