Hello
I have an update on my eggs and a question. I candle the eggs last night and I have three green eggs for sure fertile, and baby chicks moving inside. My question is if the mom is a green egger and the dad is a blue egger, what will I get? I mean if one of soon to hatch chick happens to be female, would she lay green or blue eggs?
Thanks
Short answer - The combo above will most likely give you green eggs, or possibly (but not likely) some shade of brown eggs. True blue is almost a zero possibility.
Long answer - (I am fascinated by genetics, so only geeks like me need to read further)
Egg shell color genetics can be complicated as you are dealing with multiple set of genes. But there are two main ones to work with:
1 - blue vs white. This is the true color of the shell and goes all the way through the shell, so if you rub the shell with an abrasive, you can't remove the blue or white coloring. Blue is dominant and white is recessive. Birds with one blue and one white gene will lay eggs with a lighter blue tint than eggs with two blue genes.
2 - brown. This is a color layer applied to the surface of the shell and can be rubbed off the shell when it is still wet right after the egg is laid. You can also buff off the brown color from the shell with an abrasive after it dries. There are actually a couple of genes at work here that determine the amount and thickness of the layer. The more intense and thick the layer, the browner the egg. This accounts for the variety of brown tints you can find from no brown all the way up to chocolate-looking.
Now when you combine the two it gets complicated.
If you have no brown layer, then the full base color of the shell is shown.
If the base shell color is white, then whatever brown layer is added is what color the egg appears.
If there is a blue shell color present, that is where you get mixing of the colors. If the brown layer is light, you get green egg color. If the brown layer is dark, you get olive egg color.
In your mix above, there are a lot of possibilities, but we can limit them down some. The mother must have genes for some light brown layering as she has green eggs. She will pass this on to her offspring. The question is with base shell color. If she has only blue egg base color genes, she will pass on blue. This combined with the brown layer will give you green eggs no matter what genes the father has. This is the most likely scenario.
If she has mixed white and blue genes then she will pass 50% white and 50% blue to her offspring. If she passes blue, then you are back to green eggs, no matter the males genetics.
If she passes white color onto her her offspring, then here is where the males genetics have a say. If he has only blue egg genes, then the offspring have one white and one blue gene. The blue is dominant and you are back to green eggs......
If he is mixed white and blue and passes on the white gene, then the offspring will get white from the mother and white from the father and have two white egg genes with a white base color. This means the brown layer gene will determine the shell color and the eggs will be some sort of brown, probably of the lighter brown variety.
If the male has any sort of brown genes in his background, he will also pass on genes to add a brown layer and you will have green eggs, possibly of a darker green than what the mother lays.
they don’t have 5 toes and their skin is light so they are definitely not silkies . I am so upset that RK is misleading their customer as far as chicken breed . So right now I don’t have a clue what I have , they all have feather feet . Can someone tell me what breed these three chicks have please ? I took three photos of each chick
