what a sweet mix!
This one looks like a silver appleyard except the bill is a different color, its going to be a real treat seeing how they all feather out
Silver appleyard ducklings
Thats so good of you, The B complex vitamins you get at feed stores are great for weaklings and the whole flock too
Or pharmacy B complex vits are good too but its not as concentrated
What breeds did you get?
I use coconut or olive, Mineral oil is a lacitive when taken orally, and used to finish wood butcher blocks. it might not hurt the duckling but then again it might burn their eyes or poison them i just dont know
