Hi,
First off sorry for your loss, Mistakes happen and its mostly the dogs fault.
Secondly yes, I've had an extremely similar experience, Someone let ferrets out where I was keeping my chickens and I lost them all. I went over the next morning and it was a slaughter house, Everything was dead, and in tact apart from the heads. If not in a un-recoverable position. I did try give the chickens that survived a fighting chance at life but it just wasn't happening resulting in me having to kill them to prevent suffering and I hate killing chickens especially. I lost some extremely caring, lovely, good looking & rare chickens and ended up giving up poultry keeping for about a year out of guilt and only just started up again.
The best thing you can do is getting some more birds, If needed and try forgetting what has happened.
Good luck, and again sorry for your loss.
