what would it take to create Autosexing Delawares? can you help me?
Silver Welsummer Hen is your ticket to Autosexing Delawares, pretty easy Autosexing project, kind of like the Rhodebar project where going back to Parent line with e+/eWh F1 but easier as the Parent on this case is already barred and has good type..
what is e+/ewh and what is going back to parent line?
you see eWh is the wheaten e allele, impossible to autosex, so we need e+ from the silver welsummer so a cross of both breeds will produce e+/eWh chicks, this males will be cros back to delaware to produce better e+/eWh chicks...
keep us updated on your project
You can not produce an autosexing delaware. The breed is either autosexing or not autosexing.
I am going to have to disagree with Marvin. Hybrids are not an autosexing breed; especially columbian restricted birds. There is not only the problem with columbian restriction but the birds are also hybrids. If you cross the two hybrids they will produce some chicks that can not be autosexed. The addition of the wild type allele at the E locus ( a wheaten/wild type hybrid) can produce striped backs on the hybrid chicks but the columbian gene will lighten the color on the back as will the barring gene.
Quote:since chick color Down is not part of any the SOP I doubt Autuosexing Delawares would look any different than your every day Delawares and the SOP is all about phenotype not genotype right?
Quote:Tim I did said to keep breeding back the e+/eWh birds back to Delaware parents as to make them true delawares and not Hybirds(F1 cross)... Columbian and Autosexing trait(wildtype + sexlink barring) dont conflict with each other, case in point Rhodebars
Quote:Rhodebars are Wildtype Barred Columbian restricted and their chicks are Autosexing so its possible Tim
