Good information, especially for those not familiar with how recessive genes work.
BREEDERS: Recessive genes live FOREVER. When you breed a recessive split (of ANY kind) to a non-split, 50% of the offspring will be split. You cannot see that recessive; you will not know which ones carry it and which ones don't. If you then sell that bird as a non-split or toss it in a breeding pen, it will continue to produce 50% hidden splits and eventually that recessive will pop back out when two copies meet. They can hide for many many generations before showing up, and by then can be dispersed heavily in a line or breed. This is why breeders say "recessives live forever."
Common recessive colors:
- Recessive White w
- Mottled mo
- Lavender lav
- Brown/Partridge eb
Other common recessive traits:
- Single comb
- Silkie feathers
Common recessive faults:
- Split wings
This seems to be an area of common misunderstanding in chicken breeding. Currently it's causing a whole bunch of mottled babies to start popping up in solid color breeding pens. Why? Mottled is super popular, lots of folks are working on it, and splits hide easily. They're getting shared (probably unwittingly), worked into lines where the breeder has no idea, dispersing the recessive widely in populations, and then popping up like adorable little mottled popcorn nuggets in incubators from Florida to California.
The same happens with single combs, and has for a long time. Lines become known for it. Why? Because someone kept that beautiful single comb bird who had everything else right, bred it to proper combs, got all proper comb offspring and said "problem solved." Except that every single one of those babies is a single comb split, and they spread their recessives far and wide. The more popular the line, the farther the reach.
Another more innocuous example is recessive white. How many of us have had a surprise white baby out of any number of color pens? Whites are often used to set type, and that recessive is everywhere.
Edited to add: The MOST common recessive in Silkies is brown/partridge (eb). It's the base for the whole breed, and can pop up in just about any color pen.
Once well established, recessives are damn near impossible to w**d out. Take this knowledge and do with it what you will, and do make sure you understand what kind of gene you're working with and how your breeding decisions impact future generations.
One of the best pieces if advice I've had is this: Think 5 generations ahead.
