Silkie thread!

Barring is dominant but it is MUCH easier to get it from a barred roo because he carries two copies of the gene. Females only carry a single copy. Using a solid coloured male with your barred girl, you could end up with 50% of her male offspring carrying 1 copy of the B gene. (They would be dark barred on whatever colour you are using because they are only carrying one copy of the gene.) If you then crossed one of those males back to his barred mom, you would end up with more barred birds, male and female, to work with, also some light barred males that would, conceivably, be now carrying two copies of the gene.
Your going to laugh at this,I just went out to the coop and that cuckoo was crowing,I was positive it was a girl becauseof the top knot being so full and round,my other ones that are rooster have that swept back look to the top of the head,so now I guess I have the two gene`s I need,so let me see if I understand this,if he breeds a solid colored girl I will get a barrred chick or is it just 50% that I will get one?

Okay, re-looked at the photo, and it could be a cockerel rather than a crowing pullet. He does not look to have two copies of barring (unless someone has been working on cuckoo, I doubt he would). So toss out my earlier comment about no girls with barring. Assuming he has one copy of barring, about half his offspring, irrespective of gender, will receive a copy, and about half won't.

Hopefully, your boy is carrying 2 copies. Boys can carry a single dose (B/b+) or a double dose (B/B). The light boys are carrying 2 copies. Darker boys (that look like girls) are only carrying one copy. You'll get better at judging that as you work with the barred birds. That said, it works differently if you are starting with a male B bird. Male with single dose of B on solid female will give you 25% B/b+ males (they will appear barred but are only carrying a single barred gene,) 25% B/- females, 25% each, male and female, of solid off-spring. But, if he is carrying a double copy of B (B/B) you will get ALL barred offspring (single dose) which will give you MUCH more to work with next generation. So here's hoping he is carrying the B/B you are looking for!!!!

Second generation barred to barred will then give you some B/B offspring.
 
so i see so much talk about genetics...and it has me wondering where you all get the information from... this might sound like a dumb question but is there a big book on silkie breeding genetics??? currently not breeding, not really sure if i want to .... but i would like to be sooo informed like the rest of you

which books, or what should i be reading up on ?

Silkie genetics are not different than the genetics of other chickens

A couple of good starting points are Genetics of Chickencolors and Basics and Poultry Genetics for the Non-professional. Depending on what you already know about genetics in general, there are others that are more in-depth.
