Pink or blue?

I didn't read through Cyprus' post, sorry. ;) kinda wiped out, been busy today.

on the pink egg shell, it is a variation on brown, it has to do with the thickness of the bloom on the outside of the shell, which is genetic. it's possible that it could give daughters eggs a pink outer layer, if crossed with the BCM it could make a grey color shell it kind of depends on what you're starting with too.

there's no real guarantee though since hen egg shell color does have a larger influence than roo genetics on the offsprings egg shell color.

you are more likely to get more variety from the "blue shelled" roosters offsprings eggs, you should get some nice olive eggers from you BCM

With the "pink egg" roo you are more likely to get variations of brown shelled eggs from his offspring which would include lighter greens.

here is an egg shell color chart that I came up with I don't have the work done yet to show what would come up based on parentage, but it might help.

from your isbar and the pink roo, you would be likely to see o o white, o o tint 1, O o blue, O o green 1,

from the BCM (not sure what number your hen is showing on the darkness chart, but oo tint 6 is meant to correspond with the BCM chart #4 color. and the color would likely be between o o tint 4 to o o tint 6

with the blue roo, your isbar's offspring would be more likely to lay OO blue, OO green, Oo blue, Oo green

your BCM off spring again assuming BCM chart #4 could be Oo green3 to Oo green 5

(I'm sure this isn't perfect, infact I think I have missed the possibility of white or brown in there.... But as I said I'm pretty tired.)

Agreed. This is some of what I stated.
I covered F1 genetics and the possibility of white and brown eggs.
 
Pink is a variation of brown.
The only info gleaned from the color of the egg they hatched from is the color that the mother laid.
Without knowing the breed of the father much of their egg color genetics is guesswork.
In fact, EE are a total crapshoot in just about everything.

That being said let me delve into the complicated monstrosity that is egg color genetics. Grab your popcorn. :pop

A Hen and a Rooster each carry two genes for egg shell color. These genes are autosomal, meaning they are not linked to the sex chromosomes or are not sex-linked.
With egg shell colors there are two true egg shell colors: white and blue.
White is the wildtype (o) and is recessive. Two copies are needed to produce a white egg.
Blue is dominant and therefore will always affect egg shell color via tinting when present. Hens with this gene will lay eggs that are a variant of blue or green/olive.

Now, let's look at the mothers of these two cockerels.
Pink egg: what I can glean from this is that the mother does not carry the blue egg gene. Assuming that the mother is ALSO an Easter Egger my fair assumption is that she carries one brown copy and one white copy (as she likely would lay a more solid brown colored egg with two brown copies). Regardless, she does not carry the blue gene.

Blue egg: This mother DOES carry the blue gene. With the egg actually presenting a visible blue it is fair to assume that the mother either carries two copies of the blue gene or one copy of white and one copy of blue.

Now, past the mothers is where things get complicated. I will exercise several different scenarios.

Let us assume that the mother who laid the pink egg mated with a father who has the blue egg gene.

If the father has one blue gene (heterozygous blue) split to white (o) then the possibilities are as follows.

Female, 1 brown copy, 1 white copy x Male, 1 blue copy, 1 white copy:
Offspring could inherit:
1) 1 brown, 1 blue
2) 1 blue, 1 white
3) 1 brown, 1 white
4) 2 white

Female 1 brown, 1 white x Male, 2 blue
Offspring would inherit:
1) 1 brown, 1 blue
2) 1 blue, 1 white

If the mother who laid the blue egg mated with a father who carried one or two blue genes the results would be as follows.

Female, 1 blue, 1 white x Male, 1 blue, one white
Offspring:
25% homozygous blue
50% heterozygous blue
25% homozygous recessive white

Female, 2 blue x Male, 1 blue, 1 white
Offspring:
50% homozygous blue
50% heterozygous blue

Female, 2 blue x Male, anything else
All offspring will carry one blue gene.

Female, 1 blue x anything else
50% of offspring will carry one blue gene.

Okay, so there is the long winded answer. :th

In summary, your best bet is to go with the male hatched from the blue egg.
He has a better chance of carrying the blue gene than the other one.

If he DOES carry a blue gene depending on what else he carries the resulting offspring from him will lay variangly.

If you want the best chance at colored eggs cross him with the Isbar.
If he has only one blue copy, 50% of the females from that cross will lay blue, 25% will lay brown, and 25% will lay green.
If he carries two copies, 50% of the female offspring will lay blue and 50% will lay green.

Cross him with the Wellie and, if he has one copy, 50% of the female offspring will lay green and 50% will lay brown.
If he has two copies all of his daughters will lay green.

Hope that helps you decide :)

Thank you. Now I do not have to be a responsible person and write a long answer to this thread.




Good job! :clap
