Take care of yourself and family.
DH & I got that nasty flu bug last month. We are still fighting it.
It just doesn't seem to want to go away. We even had to pay a neighbor kid to come and care for our animals for over a week because we couldn't get up to do it. We lost a few baby rabbits because of it, and our horses lost some weight, but everybody is recovering along with us.
We couldn't get anybody else to take care of the animals, and he didn't really know how to do it with us giving him instructions through a closed door. We didn't dare let him in to talk to him, we didn't want to spread the flu. This is a nasty bug, and I'm glad you found someone to take the emu chick while you are so sick. (She) will be fine with her foster parents until you get better.
Get lots of rest and don't try to do too much too soon, or you will have a re-lapse.
Take care
Jean
