Everything Under the Moon

I don’t know where else to speak about this. Iv has an emotional weekend. I’ll try to include the details so maybe you can help me. I have a flock of ducks. One that I am very connected to. She is all black and the rest are multi white and grey. Have had them for a few weeks. They are 9 weeks old and getting pretty big.
Saturday night - I had some bad news and was very emotional. I sat next to my garden ( that house the ducks ) just watched the sky and tried to ground myself. I finally went in around 4am.
Sunday morning - I go out and one duck is missing... my favorite. Well I find a pile of feathers, and her whole heart. Like it had been gently removed. No damage. 2 valves at the top just knarley to see it in its condition. Well no bones, no beak, no feet, nothing. Nothing anywhere in the yard or fields or bushes. The feeling of loss was there but more so the dealing of fear and negativity.
My question is. Is this a demonic message? What on earth could such a morbid message be. I feel it’s more than just a dead duck. It’s a message.

I'm really sorry about your loss, that's terrible.
I'm more inclined to think it was a raccoon or some other such predator.
I had an incident once where I came home to a dead rabbit, when I felt I had disrespected a plant... one associated with death, that was my punishment. In retro I don't know what happen to the critter but I don't feel it was evil. Just some bad circumstances.
Try not to be too washed away by this, instead pay a tribute to your pet, maybe make something with his feathers?

My feeling is that the duck was a guardian angel. Her heart was left behind, intact, to let you know that she will always be with you. I really don't get a sense of anything demonic.

I guess because of my emotions the night before is what’s making me feel it’s a message
