Our little brown silkie has been living inside for a week. We separated him out since he hatched early and the mother would have left the nest to take care of him instead of sitting on the remaining eggs.
He's getting held a lot and will fall asleep in your hand. We often take him out and he'll follow us around, and will peep loudly when we leave the room.
I do think he likes this little bear -- this morning the bear was inside the tank and he was sleeping against it. This has been a lot of fun for the family, but in about a day he'll have to join the other chicks outside.
Update: This one is not assimilating with the others and will be raised inside for now.
