Ok, first of all, tell the guy who got on his high horse to your husband about chickens being "just chickens, not pets" to go fly a kite, maybe near a power line.
Most of us so called backyarder's who keep small flocks care very much about our chickens. We love raising them, have invested a lot of time, effort and money into raising them, and do not care to see them shredded.
Then you can tell your husband that yes, farming is hard work, however, keeping chickens is not. Hard lessons have been learned, there's no reason at all not to fix what needs fixing and try again.
Then start thinking about your next coop and how best to secure it. Wire aprons have been discussed, someone mentioned running a few strands of hot wire around the coop. This is an excellent, inexpensive and easy to install deterrent, has worked for me for years.
Good luck, I hope you work it all out and end up with a nice little flock of good layers!
