They hide illness so well it could have been something going on for a while and you just didn't pick up on it. Another reason for me I want to keep my flock at a number I feel I can keep up with so I won't hopefully miss something. Not saying your ignoring your flock but they just hide sickness sometimes until it's too late.
I'm very sorry so hard to lose them.
I know chickens can die of fright not sure about water fowl.
Pear just died also. Perfectly fine this morning, around noon he wasn't chatting us up, around 2 he was closing his eyes while standing, rushed him to the vet and they GUARANTEED me he was acting strange because his "food wasn't being digested fast enough" they massaged his crop and put some like, loosening stuff down his throat and sent me home saying he would be great. I hugged him for a few minutes then took a nap, I woke up and noticed he wasn't peeping, looking down and he was dead.
I am so furious. Why did the vet not do any tests? I even ASKED her if it was avian flu or ANYTHING of the sort and she just told me he was fine, no tests or any further exam other than feeling his crop. Outraged, devastated, frustrated.
I should've told her to do some tests, or demanded it. It was my job to help him and I messed up, I hate myself right now. He was perfectly fine this morning, too. Ran around outside, went swimming in the tub, slept in my bed, absolutely no sign of him being in distress, and when I did see the first sign I scheduled a vet appointment and it only got worse.
and now he's gone. I'm giving away all of my geese, I'm not doing it anymore without Pear. I will not be coming back to this forum. I love you ALL so much, and it's been such a joy becoming friends with you all.
