Great! Went and had a fecal done at the vet because I saw eyelids getting a little lighter than I would like. She said the only thing that was in the fecals was crypto.

Wonderful! NOT!
I have no idea where it came from or how long it has been there but this is the first time it has ever showed up on a fecal examination so obviously not very long.
I knew nothing about it so the vet told me this:
It does not normally hurt adult animals. They can be infected or carriers but it rarely casues symptoms in adults but the mortality rate in kids is high. It causes diareaha and there is nothing is they can do. It is resistant to antibiotics. The only thing they can do is supportive therapy like electrolytes and lactated ringers.
Hannah is the one who showed crypto on the fecal. Hazel is the one who just had a bout of the runs. But she said since it responded to the biomycin and neomycin that it likely was not crypto related. She said Hannah is the carrier most likely. She said that even if she showed a negative fecal that we can not assume she is negative since she once was postive. It can go dormant but they can still be carriers.
She said it will not be killed by bleach but hydrogen peroxide will kill it. The problem is that we have dirt floors and of course the patures. She said I could have them off the property for years but it will still be in the ground.

It is contagious to cattle I know but I am not sure about horses or other livestock. I assume sheep would be a no no too.
So idk what to do. Any incoming animals will have to build up an immunity. Bringing outside kids in is a no no since they probably would have the hardest time with it. I definately don't want to take animals to anyone... I don't know what to do.
Oh yeah.... and it is contagious to humans so I have to be careful when handling them. I just want to give up. Is this a sign?
