How high can chickens jump?

[Mother of Chaos]

I have one token meat bird (got her for company until the layers were old enough to join the older hens i purchased). The rest are olive eggers, Easter eggers and cream legbars or back yard mixes of the aforementioned breeds. I’ve never seen meat bird jump, but the other pullets seem to perch on the chicken wire with regularity.
I like the idea of netting though. Would this also prevent raccoon invasion from the top? One night we saw them scale the 6 ft fence and had to beat it off to protect the ladies.
Is there a concern about them getting stuck in the netting? What kind of netting should we use?

Of my five, two are Easter Eggers who seem to regard our six-foot perimeter fence as their personal roost. Edit to add: The other three (barred rock, buff Orp, and speckled Sussex) are more gravity-bound and not interested in such foolishness.

I’m ordering the heavy-duty netting recommended above.

For those that have it, do the birds ever get stuck in it?

As far as I know, none of my birds have tried to escape with the netting. The twine diameter isn't quite as thick as the welded wire fencing around the bottom, but it is thick enough that the chickens seem to know that they can't get through it.

We will definitely look into that netting. Thank you!!
For those that have it, do the birds ever get stuck in it? I’m just afraid my very pretty but not always smart girls will try to get out and become injured, or worse, if they get stuck.

They shouldn't get stuck even if they fly up and hit it, but there's always a tiny chance of something that shouldn't happen, happening.

I did find one of my pullets with an injured leg and feathers on a vertical portion of the netting, as my netting drapes over a portion of the side of the run to form the upper 2' of the run "wall." Since I did not see it happen we can only assume she somehow got her leg tangled in the side netting and cut herself during her struggles. https://www.backyardchickens.com/th...es-it-look-w-close-up-photo-of-wound.1647155/ (and yes she's fully recovered now).

Best to attach the netting as taut as possible - not so much that you are straining it or stretching it, but a fairly taut netting will let birds bounce off of it if they do happen to hit it. You are more likely to get tangles with any loose draping (and this goes for wild birds trying to get in as well).
