Show off your Delawares! *PIC HEAVY*

I believe he was about 14 - 15 weeks.

Was he from one of the project birds?...

And I too would have liked to seen what he looked like filled out. He really looks like he has it "going on" for a bird that age.

No, he was not from my project birds. The project birds, F1s are all barred. They are just at point of lay, so should have some F2s coming up soon. The F2s will be a variety.....

"Mating these F1 birds together will produce (in a large hatch)
Barred;Black;Delaware;Split gold/silver males;Buff Columbian; Barred Buff Columbian & Silver Columbian (the last will be pullets)
in the ratios 18:6:3:2:1:1:1"

We need the Delaware males and the Silver Columbian females for the F3s ......
Hopefully, the F3s will all be Delawares and breed true. Then, to work on the details.......

I think you're going to be having A LOT of chicken dinners with that ratio.. lol.. Of course, you never know, you may get more silver colombian females then what the statistical ratios say. "Oh the joys of genetic roulette." I'll be crossing fingers and toes for all of you on that one. Maybe even a chicken dance or two. Though, I have to admit, my projects haven't responded well to that. All the young roos just look at me kinda funny.

Have you posted any photos of any of the projects, you or anyone involved in that?..

No, I haven't posted any pictures of the F1s here.

This was about a month ago .....

Amazing how much the barring can hide.

Please keep posting progress on these in the future, I would be very interested seeing the phenotype vs genotype in these crosses as the project progresses.

Kathy, since I've had such great luck hatching mostly pullets the last two years, do you wanna send me a few dozen F1 X F1 eggs and see if I can prove the genetic ratios for Silver Columbian females wrong?

You probably already know this:

Genotype for Barred Rock is E/E S/S Co/Co B/B
New Hampshire eWh/eWh s+/s+ Co/Co b+/b+
Co is epistatic under E so is not displayed.
Mating these two breeds together results in birds with the genotype
BR male X NH hen all Barred birds
E/eWh Co/Co B/b+ S/s+(males) or E/eWh Co/Co B/- S/- ( females)

Yes, Jeremy! That is what I should do! There is gonna be lots of hatching going on, for sure!

Yes, I've read a lot on that. Are you sure that the Barred rocks you've started with are all E/E?

Once you get to the next generation, should be easier to see segregation in chick down phenotype alone.

I've read that many are/were E/eb. In fact I'll have to see if I can dig up the paper I read on show vs production genotype in the time period when the Delawares were created.
