I understand how heart-tugging it can be entrusting your baby to the "big bad world". However, Silkies are pretty mellow bunch, and as they are just giving her the occasional peck, sound like they will accept her, but just want her to know that they are NOT her Mommie.
If this gives you heart - here's my recent story.
About 4-5 days ago, I went into the barn, and heard miserable peeping. I finally tracked it down to an abandoned chick - obviously just hatched as she was wet - I have no idea who the Mom was - I've several broodies, but she was away from all of them.
I took her out, and put her under a heat lamp in my office. She still didn't look viable, and I'm really sick of the heartbreak of tending these newborns only to have to euthanize later. Therefore, early evening, I put her under one of the broodies, and watched for a while. The young hen looked kind of shocked, but didn't immediately attack the newborn.
The next day - the chick had transformed from not viable to a healthy rounded fluffy chick full of piss and vinegar. I could tell because she was sitting on top of her new Mom.
My watering system isn't set up for chicks (I've got more than 700 chickens), so I've now got foster Mom and chick sequestered in a large dog crate on my porch. Not only does the foster Mom LOVE her baby, but I've had passing pullets charge me, if I attempt to scoop up the chick if she wanders out of the dog crate (she's still small enough to slip through the bars).
Your baby will not get the mothering mine did - as mine was a new hatch. However, the very fact that she's not being bullied is a good sign, but I'd certainly watch out for that, and step in if necessary.
Good Luckl
