Breeding for a Yellowbelly Pied

[cinderbird]

yellowbelly is a codominant gene:

yellow belly x normal gives you - 50% normals, 50% yellow bellies (each egg as 50% chance)

Ivory x normal will give you all yellow bellies though (maybe this was what you were seeing?)

yellow belly x pied - 50% normals, 50% yellow bellies ALL 100% het for pied

Take 1.1 yellow bellies het pied and breed them together this will give you the possibility of having any of the following:
- 66% het pieds
- yellow bellies 66% het pied
- yellow belly pied
- ivoy 66% het pied
- ivory pied
- pieds

Take a yellow belly het pied and breed it to a pied and produce:
-100% het pieds
-Yellow belly pieds
-yellow bellies 100% het pied

I cant remember the break downs for the % of each possibility right now. Hope that helped though
