Coop inside barn, amount of screening to use

[annagoodspeed]

Hi, I am building a coop that will be a room inside a larger shed. Since any drafts will be cut by the shed, is it ok to make the two inside walls half heavy gauge hardware cloth? Not sure if so much visibility while roosting would be a stress factor for them? They will have a solid wall at their back, a window on the south and and screening on the front and other side wall, Extending to the ceiling from a knee wall about four feer high or so.
Thanks!
