chad&denise,
One of the white ones *appears* to be part lab, it has the lab muzzle, at least to me.
Also, dont count on just because a lab is yellow the pups will be yellow, labs have been know to throw all three colors in the same litter.
My boy was out of a yellow mother and a black father, the mother was black factored, but had thrown all yellow litters prior to this one.
Also I have never heard of litters having multiple fathers, I thought that once she was bred, she was bred.
Crayon herself looks like heinz 57, but she's cute in her own way.
Good luck with finding homes for the pups.
