Last year we had three silkies hatch out eggs. We only gave them5-8 bantam/silky eggs each and had a good hatch. We didn't get them all under them at the same time so when one or two would hatch and get all dry and fuzzy we would take them inside to our brood box that way they grew up friendly and thinking of us as their moms the hens didn't seem to notice anything. Once all the eggs hatched we would open the top to the cage and let her rejoin the rest of the flock usually by night she would realize she was free and when we would go out to lock them up she would be in the big coop. I have lots of pics but to lazy to upload them right now.
Good Luck!
