100% pied to a normal =
every egg has a 50% chance of carrying the pied gene, aka all the babies are possible (50%) het pied.
Keep all the female babies and raise them up then breed them back to dad. You have a 1/4th chance of getting a pied, assuming that the female you breed him too actually is het for pied.
The possible offpring from Het pied to Het Pied=
Pieds
66% het pieds (each parent has a chance of contributing a copy of the pied gene)
normals (babies where the parents did not contribute a pied gene)
the hets and normals look the same, so you have to breed them to figure out which ones are which.
