Sorry for the delay in silkworm updates. We were away for awhile. So I've got 3 silkworm posts all at once here now. They've been busy little caterpillars!
So here they are at about 15 days after hatching. They are about an inch or so long, but several are much smaller. Still just eating and pooping.
The one book I read that mentioned how to handle them said that at around this big it's okay to pick them up by hand (when they're smaller it recommended using a paint brush to move then if needed) but when I tried picking them up, they still felt awful small and fragile. I didn't want to let my 3 year old handle them yet, because I'm sure she could have easily hurt them without meaning to.
