Chick jumping out problems

[GooseBee]

So I have 22 baby chicks. Only one died as baby chicks. There getting bigger and jumping. So I have problems. chicks have pen they sleep in and in day time I put play pen out so they can go in and out of there chicken house into play pen and sun bath or just sit. Well play pen is open on top and they like jump out , well many times they almost got hurt by older chickens and other time almost got hurt by goose. I do have chicken wire but I can’t unravel it. So I tried put all of them in area were older chicken stay today well I didn’t notice there is a part were they can escape so they all escape so I had to put them back in house. Also I do check on them but like almost every hour there one or few that escape from play pen. Also I can’t unravel chicken wire because I can’t figure it out and is been little stubborn.What should I’d do? Also here is some pictures of my beauty chicks there getting big. There little brat chicks but I love them so much.

Baby gates sometimes work really well to extend and put on top of the playpen

Can you get some plastic poultry netting and clamps at a local home store? You can cut some large sheets and just clamp it onto the sides of the playpen.

You can also open a cardboard box and set it on top.
