I am so sorry for your loss and the extra stress. First advice is to not google things, google isn't always right. I would suggest posting here first, then we can all have a conversation to help.
On my end, I come from an enormous family because it is huge we have many deaths a year. I am not numb to death but because of this our entire family focuses on the good in a bad time.
Animals are worse to lose because they don't live to be 100 years old.
But I still cry over deaths human or animals and I look to the positive side.
It is tough but I try to let mother nature take control with the aid of myself and medicine when needed. Usually when chicks die so young, they wouldn't have had a chance growing up, there is something wrong that we humans can't fix. But they had a great loving home and they left little chick foot prints on your heart.
You can always post pictures, videos, or just a question no matter the question, we would all love to help in any way we can.
