You guys might also want to use a self-blue (Lavender) colored bird to this. Blues and splashes carry pattern genes (lacing) that will conflict with the penciling. You won't know for sure until you would breed the F1's together to see what would happen, IMO. By rights you should start to see penciled birds. The F2 generation is where the fun starts. You will have to breed a ton of birds, and you will get only a couple of what you want. You should keep a son, and breed it back to the mom........................... So many possibilities :- )

YAYYYAYYAYYA I sooooo am gonna fall for TINK!!RoPo has my two new sikie hens in her hands and is bringing them back from Ohio today. My new roo comes next Sunday. That will complete my quad for starting my calico pen. I am super excited!!
Sally is taking Tink (splash silkie hen) which means I have one more splash hen available.
That is the EXACT book I want!! here is a look inside of itA good book to get on genetics would be the chicken color genetics book I mentione previously. When I did reserach I found out the book was written by a fellow named Jerry who introduced the US to the serama breed. But the book is. . . . .like $100 if I remember correctly, so I am waiting around until my bday and use that $ on gettting myself a copy of that book. (now, not to mention I want a whole flock of seramas to add to my collection after the research)
To check out that genetics of colour book again, here is the site. It downloads and you can only view the download once and then it disapears.
