Pullets roosting

Hi all
My nine seekers have taken to roosting on the six foot wire partition dividing their run from my hens. When I go to close the coops for the night the legbars panic and fly into the main run and it takes ages to round them up.
Question- are they too young for wing clipping?
My run is very secure so I'm not so worried if they roost but there's no doubt one of my hens would attack them if she found them in the main run and the legbars are really small.

It should have said nine weekers ( predictive text problem)
So a higher barrier called for.
Thanks for advice

Personally, because i let my chicks into the garden, while im out there, i wing clip at around 2 months ( 7-8 weeks ) as i wont be running around the gardens/alley trying to catch them.
