Is this egg fertile from my 5 ISA browns without a rooster??

[Chicken_keeper88]

I think there's a break down in communication here, but good luck.
Those breeders sound sketchy, based on all Information given.

And not sketchy just a lovely old couple that was back yard breeding chickens in there garden at there house.. not everyone owns a farm or land unfortunately.. in UK England it is expensive to buy land n very expensive to buy a farm so some people including myself need to do it in there garden at home .. I don't see what the problem is? Isnt this forum called "back yard chickens" coz it's for people who raise and breed chickens in there back garden???? Did I miss somthin here lol????

How do U explain this information then and the fact that mine does infact have the circle around the dot clearly and not just a dot without the circle..View attachment 4003499View attachment 4003500

I explain it as:
it works pretty often, but is not 100% reliable.

There are a few people on the forum with hen-only flocks, sometimes for years on end, that sometimes find bullseye spots on their egg yolks.

It might be parthenogenesis (when the egg starts to develop without ever being fertilized by a male.) Such eggs will typically not produce live chicks if you incubate them. Here is an article that talks about it, although it's not exactly an easy read: https://www.thepoultrysite.com/arti...-normal-fertilization-and-embryonic-mortality

They exclusively only bred ISA browns.. in there personal house and back garden away from any farms etc, and when there for myself anyways il take a gamble..

Do you mean they have one kind of rooster and another kind of hen and the chicks are ISA Browns?

Or do they have ISA Brown hens and ISA Brown roosters? In that case, the chicks will not be ISA Browns, they will be mixed breeds that do not always have the same traits as their ISA Brown parents.

ISA Browns are a hybrid. They come from a cross with one kind of rooster and a different kind of hen. A special thing about ISA Browns is that males and females are different colors, so it is easy to sort males from females at any age. When you breed ISA Browns with each other, you completely lose the ability to sort the sexes by color. Both male or female chicks can be colored like either sex of ISA Browns, or like either of the original parents of the ISA Browns, or sometimes other colors yet.

Breeding ISA Browns with each other will usually give nice chicks, which can be healthy and good layers and a variety of attractive colors, but they will not be ISA Browns.

The first thought that came to mind was immaculate incubation.

Hi, welcome to the forum. Glad you joined.

Check out "blood spots" in the egg quality guide.

Egg Quality Guide - The Poultry Site | The Poultry Site

Blood spots have nothing to do with a rooster. The yolk is surrounded by a membrane as it grow to the size to be released to start an egg through the hen's internal egg making factory. That membrane is covered with blood vessels to bring nutrition to the growing yolk. When that membrane splits to release the yolk to become an egg, it is supposed to split along a line that has no blood vessels. Occasionally there is a mistake and you can get a tiny drop or fairly large amount of blood inside the egg.

From the time the yolk is released to start an egg it takes about 25 hours on average for an egg to be laid. That egg can only be fertilized in the first few moments of that journey. That means the fertilized embryo will be at incubation temperature for about a day before it is laid. The hen's internal body temperature is a little above ideal incubation temperature but the embryo can handle that. So the fertilized embryo is developing all that time. That is what causes the ring around the white dot of a fertilized egg. It's basically the waste byproducts of the embryo's growing. Once the egg is laid and cools off that embryo almost stops developing. If it totally stops the embryo would die but the rate of development is pretty much negligible. You are not going to see any further development unless it is kept at warmer temperatures. Certainly not enough to see blood or any parts of the embryo.

I don't know why you are seeing what you are. I've never paid attention to the dot in cooked eggs. Parthenogenesis is a real thing, you can do an internet search. It has been observed more in turkeys than chickens yet it does occur in chickens. Sometimes they do hatch, always a male when they do. I don't know if that is going on with yours or if it is something else.

I encourage you to incubate those eggs. I really do not think they are going to hatch but it doesn't hurt to try. I think you will feel a lot better about it if you try. When you give up on those eggs please gently open them. They can be kind of runny after being at heat that long so try to not break the yolk. Look for any development, probably blood vessels more than anything else. If you need photos of what to look for let me know and I'll send a link.

Let us know how it turns out.

They did say they was ISA brown hybrids so maybe they have done this and used males from there stock to fertilise females I think she might a said they was ginger X ISA browns so maybe that's the case.. and yes I know already done alot of research into ISA browns amd there sex linked traits from breeding a white breed into road island reds or lhoman browns or both bred to either road island white or white leghorn or both some even are sayin light Sussex.. or I think that cud be the amberline.. thanks for that tho

there's actually a really good thread on the isa browns breedin linage on here that iv been tryna make heads n tale of which breeds they mean when they are talkin in there breeding codes for different breeds n different generations.. i kinda understand some of it tho as bred chameleons before and bred other things.. so I know what f1's f2's bx's etc mean at least so that's a start lol

The thing that winds me up is I was gonna go to the area next to my area over weekend to get a free white or light dekalb rooster but car broke so I cud av potentially made a amberlink or ISA brown type chicken if I am reading correct but missed out on him coz my stupid car.. I shuda just got a cab..

For ISA Browns and the many other red sexlinks, it really works out to:
--a company develops one line of red chickens
--a company develops one line of white chickens

Crossing a red rooster with a white hen gives the color-sexable chicks to sell.

Beyond that, it's all details. For example, the "red" chickens may have originally come from Rhode Island Reds or New Hampshires, or they may have large amounts of Leghorn to improve the laying ability, or quite a few other possibilities, with all those things being many generations back. The red chickens may actually be two lines that are crossed to produce the roosters used to breed ISA Browns. Similarly the white ones may come from various original parent breeds, and there may be two lines of white that are crossed to produce the mothers of the ISA Browns.

Some of the big breeding companies have many different lines of parent stock, each of which is treated like a pure breed, but then the company can cross the lines in different combinations to get different hybrids.
For example:
https://www.dominant-cz.cz/en/
If you look under "products," you can go to a page of brown egg layers, or white egg layers, or whatever. They list many different kinds, and for each one they show the male & female parents, the young chicks, and the male/female adult colors of the chicks.

The main points I see:
--ISA Browns have red father/white mother, which gives red daughters/white sons.
--Amberlinks have white father/red mother, which gives white chicks of both sexes.
--Both of them are very good layers, just like their parents and grandparents.

Other than that, the thread goes into lots of detail about the exact genes involved. I would guess it's college-level stuff, although I don't know for sure.
