how accurate is the color calculator? i use this one http://kippenjungle.nl/Overzicht.htm#kipcalculator just wondering, because im getting a start on the lavender orpington project next year and am figuring out pairings that will produce blacks because im not a fan of close linebreeding if it can be avoided. Also orpingtons are rare in my area so i would be happy to be able to offer any color other than the usual buffs for sale next season, one reason why i want to avoid linebreeding closely. I have lavs chicks im growing that were already linebred (parents were related), and bbs chicks im growing that were already linbred (parents were related), and another line of buffs (not linebred). There is only one source in canada i have found these birds in bbs and lavender, so finding another supplier is really not an option, which is why i want to introduce buff and cross the colors this way, i realize it is not ideal, but this is where i have to start. im building indoor breeding cages for next spring so i can breed pairs and trios and see if the color combs work as they should. I had access to a very limiited number of bbs eggs, im holding out much hope of the 6 in the incubator at least ONE is a black, so i can breed lav to black for blacks carrying the lavender gene, and then cross them back to the lavender adults, getting a % of lavender offspring (for 2012). lavender X buff= black lavender X blue= black & blue lavender X splash= blue lavender X black= black (split for lavender) buff X splash= blue buff X blue= blue & black are any of these pairings likely to produce mixed colors, or color leakage? or anything else i need to be aware of? i realllllly wish i had access to more lav or bbs eggs, but thus it is not the case silly canada.
