Where can I get breeding and genetic info, calculator or formulas etc?
some info to see what colors you get matched whit best colors Orpingtons.
I always see people give formulas and gene calculations, but where do they get that information?
I use Kippenjungle, Henk has done a ton of amazing research <3 http://kippenjungle.nl/kruising.html and http://kippenjungle.nl/Overzicht.htm#kipcalculator It can take a while to get used to (and theres a bunch of other calculators too!) but it's VERY handy for genetics : D I'm sure there's other sites too but this is the #1 calculator and place I go to <3
The color calculators for chickens that most of us refer to regularly are the kippenjungle calculators. This is a private website, but seriously useful! (Along the lines of feathersite.com) Their basic language is not English, but most pages have very decent American English language translations. The basic overview is here: http://kippenjungle.nl/Overzicht.htm
If you are breeding to show birds in the USA, you would want to look to the poultry standards books published by the American Poultry Association (APA) or the American Bantam Association (ABA). Most shows use judges trained to these standards. Each book has breed-specific information, but don't overlook the general qualifications sections for conformation and color.
Hope this helps....let us know if you have any other questions!
