Ok lol...lesson one: Chickens have a "Genotype", that is their actual genetic make up. Then they have a "Phenotype" ... Which is what they look like. Best example off the top of my head is Recessive White: not all white birds are " White" genetically. They may be any color , but if they possess two copies of the Recessive white Gene, they will look white. So if you have a black Rooster, And a black Hen that both have 1 copy of recessive white they can and will have Some white offspring. Though those offspring are Genetically Black (Genotype) they look White. (Phenotype) Now, before somebody tells me that is not completely correct.. I know it's not , but it illustrates a point well

Lesson 2: Chickens have 2 sets of Genes. One set from Mom, and One Set from Dad. In a Certain Variety of A Certain Breed, both sets are very Similar, therefore the offspring look very Similar to Mom and Dad! Lesson 3: There are only 2 colors in chickens. Black or red!! Everything else is a modification, dilution, inhibition, restriction or other form of messing with Black or Red. A good Example here is Blue and Splash. The Blue Gene (Bl) dilutes Black. Having one copy of Bl dilutes Black to that grey color...which we call blue. Having 2 copies dilutes further to that mixed up dirty white, splotchy color we call Splash. Another example would be white. White is not actually a color, but more the Lack of Color. White basically turns the black and Red Off. So how does all of this apply to Buffs? Just imagine how many different things you have to do to make a black and Red bird be solid Buff?? It takes a lot of those genes to mess up the black and red just right to get this color. Many of the genes the really smart geneticalististis folks aren't even sure of yet! So now imagine, when you breed a buff to anything not buff and you get half of those genes? Some of them dilute black or red, or just black or just red. Some of them do different things with a single copy vs Two copies, some don't do anything with a single copy, and some of those could be hiding in the not buff bird and the buff bird then Show up in the offspring half the time and not show the other half....buffs are a genetic mess!! Lol Ok...now the sad part is, I have typed a book here and haven't really taught you anything!! I have left out so much that your now armed with just enough knowledge to get it all wrong!! This is why people spend their entire life trying to get one Variety of One breed figured out! With buffs, it has taken many dedicated Poultry men several lifetimes and we are still learning! This is also why even in a simple color like Black, you cannot just breed good black to good black to get better black. Btw- black isn't is as simple as it looks!! There are pages devoted to one color, on countless forums! I think every breed club has a forum with a " How to get better blacks" thread. For me to even try to start explaining here would be insane...so I guess I did! Lol If you really want to learn genetics, you can spend the countless hours I have reading, researching and studying - then you will be as lost as I Am

Seriously, I have researched it A lot and I know very little. Which is why I defer do much to guys Like Jerry Segler, Ted Adkerson( Hope I got that right) , and many many others. These folks have dedicated a major part of their lives to this. Just a note on Jerry Segler. I defer to him a lot as I frequent many of the same threads as he. We seem to have similar tastes in birds and breeds and both really enjoy "Projects". Jerry doesn't even know, until now I guess lol, how much of a type of mentor he is to me. Basically, the guy just does stuff the way I'd do it!! I hope some day to be half the poultry man Jerry is!! I have followed his work and teaching for awhile now.
