I know you say they are in their ugly phase, but they don't even look remotely close to a Brahma. Can you tell me how many generations out they are from what you used to get the coloring?
I am absolutely in love with brahmas and when I saw what you have done with them, it honestly makes me want to start all over and just have brahmas. They are by far the sweetest birds I have, my children ADORE them and for whatever reason I have not had a problem with them in the AZ heat like some of my other breeds.
My question to you is, you are more than halfway across the US from me. How could I even get them here safely without heat exhaustion? It is hot here until the end of October.
What a time to be broke.
Those are gorgeous!
However, someone wishing to take these lavender columbians in the direction of APA show quality could easily do so since they are but one color gene removed from light brahmas which are the most established of the show type brahma.
Does this mean that to improve SOP type, you would need to use a show quality light Brahma? If so, what percentage of the ofspring would have the lavender coloration? I'm new to the whole genitics thing, please overlook my stupidity..
I am still thinking on these, they are so beautiful.
Quote:Yes, I think that if someone wanted to make these a APA recognized variety, it could best be accomplished by breeding them with show quality brahmas. Since lavender is a recessive trait, none of the first generation will be lavender, but 100% will have the gene. So, when you breed these offspring together 25% will be lavenders which will breed true and be of better type. Of the non-lavender offspring about 66% should carry the gene. You can test mate these non-lavenders to determine which ones are split to lavender, but a simpler approach is to just retain all the best pullets (2/3 of which should carry the lavender gene) and breed them to your best lavender roo. My usual strategy with projects like these is to do a couple successive generations of backcrossing and at each generation test mate the progeny to determine who carries the recessive gene. This is how I make the fastest progress.
Thank you so much. That was worded to where even I understand it.
