Thanks for all the advice, everyone here has given me a lot to think about! I have a chicken savvy buddy coming in from out of town in a week or so who says they will help me go over the coop and run after I decide if I'm going to repair or actually start over and learn again. I wasn't invested too much financially in my set-up, less than $30 in hardware, paint and free pallet wood and
after two weeks actually using it, there were some small things I already wanted to change. There were a lot of hopes and dreams put into that coop too, something just doesn't feel right now when I look out the window and see it empty.
And I'm not more than superficially angry at the suspected dog, instinct trumps all of our sense and emotion, dogs will be dogs. or possums, coons, or anything that might have been passing through. But now that I have been reminded of such a harsh lesson, perhaps I can try again with a new insight to consider.
That, or I'm going to have a flock of house chickens.
Thank you again, for everyone's time, consideration and kindness.
