Sorry to hear of your loss. Its worth a try, the birds will respect the wire. If I had to permanently coop them, I would probably cut numbers drastically! Its just not ok for me to cage them all day.
I know for many its impossible, and they keep their flocks small to allow ample room.
I have to agree on the comments with roo aggression. My polish, orpington, OEGB and maran roos are sweet and no problem. My orpington roos will even brood with the hens, and "mother" the chicks.
My EE, Australorp and wyandotte roosters will go after people. I even have a few silkie roos that challenge me! I do notice that the human aggression goes away when the cockerels are growing up, and the roos are maintaining their spots. I usually only remove roos that are cruel to their hens or other flock birds. Since my species all comingle, roosters usually wont challenge me due to my ganders standing watch. If I get attacked, that roo goes to "jail" (dog kennel) for 2 weeks immediately! Unless the gander has flogged him before I catch the roo
I have 2 boys, Red my GLW and Bruce my Australorp that are in jail "frequently"
