I'm so sorry for your big loss. But don't give up. 
I had a similar situation happen when I had to leave town on emergency. I was SUPER mad at the "oh, I got it, no problem" sitter who blew off instruction time for horses and chickens. I wont use her again. (Also $400. vet bill for horse). I think my dogs reacted- separation anxiety when I left. When I got home I promptly threatened their lives- as the alpha dog that I am and with the dead chicken in my hand- Then threw them out of "my pack" ( also known as not talking to dogs for about a week). Then slowly let the dogs back into "my pack" after they had shown the proper humility and submission. It took me about two months to get over it lol. Dogs wont look at my chickens when I am around but I will never let them be alone with them again either. Lesson learned. Unfortunately, losses are part of chicken keeping. It hurts.
I think your coop is lovely- you are most of the way there. It would be a shame for you to give up and miss out on all the good stuff.
