In the case of fox taking the birds, they often stash their kills for later meals. Some preds just kill them all for the thrill of doing so. Regardless you have my deepest sympathy.
They could be just as satiated eating rabbits or what not. But, as many say, "everything loves chicken."

Could have happened to anyone. When you don't know you have a particular predator it can take you by complete surprise. I just lost 3 to a pair of bald eagles who have never hunted our chickens in 4 years. It's the same pair of eagles, but things changed on the river , so this year they had to expand their resources. Now I'm fortified against them. I cried and cried too. I had my 3 girls for 4 years. There's more to it, but I don't want to sidetrack your post. Just want you to know I know how you feel. 
I'm so so sorry.
