I'm so sorry for your loss! In your position I'd probably want to get some little fluffy butts to raise as soon as possible. They won't replace your lost flock, but hopefully they'll help ease the pain.
We "share" our property with mountain lions, bobcats, foxes, coyotes, raccoons, skunks and 'possums. Not to mention the occasional loose (neighbor) dog. We only have 9 chickens and 2 ducks so it's been easy for us to try to predator proof our coops/pens. Our main coop has a cement floor, and the run I'm working on will have buried wire that completely covers the bottom of the run. It's a lot of work to nail the wire to the framing to completely cover the bottom but I'm hoping it'll keep the beasties out.
If you do get new chicks, I hope you'll post pics for us to oooh and ahhh over!
