I am guessing my suggestion is one you do not want to hear...
It could be a teaching moment as to "why we do not touch hatching eggs"... depending on her age..
( I know that sounds like something an old grouchy guy would say, I can't believe I sound that way)
the egg was kicked out of the nest, by the mom's, outside. I love my silkies, but it was shrink wrapped, and had she not brought the egg inside for help, the baby would have died in the shell, anyways.
She's aware it might die. She understands that, it's not her first egg rodeo.
She just hopes it's okay because she likes babies. lolDo you have any baby vitamins like that liquid vitamin to give babies after they've been real sick? I wonder what ingredients are in neutral transmission what could be used to give them instead.
I have gummi vitamins - all my kids atm are old enough to chew
