How cute!!!! All of my bantam whites hatch out 3 days early. It's really weird...If they're not hatched out by the time the LF are, they probably won't hatch. It's a good "warning bell" for when the eggs are due! 
 
She looks adorable! I usually don't have an issue with the mommas accepting babies. My Lil Ropo (gift bird!) is precious. She'll take any chick under her wing.
 
 
AND, it looks like I have white LF again. I have at least one largefowl white chick in my barracks now. It must have come from the black male and splash female. I thought something was odd when I wasn't getting all blues! I got blues AND whites from the set up! If the chicks come out looking anything like their parents, I have a feeling I'll be keeping the white LF around!
