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

[NatJ]

Yes iv come across this info/word for fertilised eggs without rooster which is why I thought why not just try and hatch them.. if it is a male only then sweet il cross that to my new breeds of egg layers off another source..

It probably won't work, but I don't see any harm in trying (waste of eggs/time/incubator space/electricity, but not a big enough deal to matter to most people.)

I know it's not just feather colour, golden comets roosters look identical to the one used for the egg layin ISA and amber's, after doing some research the golden comet roosters also give off sex linked chics to there offspring apparently, so maybe it os the correct male thsts been kept secret what they make isas and ambers with??

Regarding color:

The gold/silver sexlinks like ISA Brown and Gold Comet have a red father, not the white/red of a Golden Comet rooster.

To make the gold/silver sexlinks work, the father must be gold (two genes for gold) and the mother must be silver. The gold/silver genes are on the Z sex chromosome. Roosters have ZZ, hens have ZW. So when you make the cross, the silver hen gives silver on the Z chromosome to her sons, and a W chromosome to her daughters. The rooster gives gold on the Z chromosome to sons and daughters both. Daughters show gold because they've got gold on their only Z chromosome. Sons show silver because they have both gold and silver but silver is dominant.

The Gold Comet rooster has gold on one Z chromsome and silver on the other Z chromosome, so he cannot be used to produce that kind of sexlink chicks. (He gets red leakage as he grows up, rather than staying a nice clean silver color, but of course that doesn't change what genes he has.)

You can cross a Gold Comet rooster to hens that are gold, and get both sexes of chicks in both colors. From those chicks you can pick a gold male and silver females and use them to produce another generation of color-sexable chicks.

The golden comets are a sex link, a cross between parents where the male chicks basically hatch white and the females hatch red. The genetics in the parents have to be set up a certain way. You cannot use a sex link chicken to make another sex link because the genetics are not set up as they need to be.

You cannot use a golden comet rooster to make golden sex links.

so maybe it os the correct male thsts been kept secret what they make isas and ambers with??

The commercial egg laying sex links are the result of millions of dollars spent under the direction of poultry science and genetics professionals to develop the parents of a hen that will lay very well. They do not simply cross one breed with another to get the commercial hybrids. They spend years using selective breeding to develop two separate flocks to breed the fathers of those hybrids. They develop two separate flocks to breed the mothers of those hybrids.

Also golden comets hens are known for also having brilliant egg layin ability similar to ISA browns so it's lookingore and more likely this os the breed of rooster used to me!?

Some golden comets are commercial egg laying hybrids, going through years of development. These lay like commercial egg laying hybrids because they are. Some golden comets are crosses of regular breeds, like a New Hampshire rooster over a White Rock hen. These usually lay pretty well since both parent breeds tend to lay well but they are not the commercial hybrids.

If you breed commercial hybrid egg laying hens to another rooster you tend to get hens that lay well. If you want to use a golden comet rooster that should work well, whether he is a commercial hybrid or just a cross between two normal breeds. These hens will lay well. But don't expect to get the commercial hybrids the professionals use. Don't expect to get sex links, because you won't. You will probably be very pleased with the result when they start laying.

I have a devoted reptile room with constant temps from an oil rad and got a snake In a plastic tub setup inside a heating tray and keeping the eggs in a plastic tub between the snake tubs Nd heat mat and directly above a oil rad so it's literally no extra costs or resources used for a little test keeping temps between 32c to 37c at mo is that a reasonable temp for them? Also candle lit them today at 8 days I think and one egg seems empty with a dark round patch right at end of it and the other 2 I dunno if its coz thick eggs shell but I'm sure I can see loads of viens goin everywhere looks darker than the other one and can't see no dark patch at end of egg on the other 2.. wish I had a torch so cud take a pic as I used my phones torch to light the eggs .. keep ya updated ..

37.5 celsius is commonly listed as the correct temperature to incubate chicken eggs.

I don't have anything useful to say about the candling results.

So I managed to fashion a candle lighting torch out of my head torch n wrapping some black bags and tape around it to do the job so I cud take some photos with my phone that was using to candle em before, it has been about 7 or 8 days now since i started incubating, first is the eggs just kept in cold set of draws no viens just clear with a dark air sack at end if that's what it's called? Then the 2 iv been incubating with networks of viens it seems after I found the white dot with ring around it In My yolk from my hens.. So what do you make of that then??? Fertile eggs without a rooster for 2 months after all???

U get the idea..

Now is the 2 incubated eggs after I noticed the white dot with clear white ring around it in my yolk of my fried egg from my ISA brown hens.. clearly can see lots of network of veins everywhere??? Or is that just thicker shells? Bit of a co incident that it is only the 2 incubated eggs that have this in them and all the eggs in cold draw I checked are just totally clear with a dark egg sack at end??

I'm not very good at candling, and even worse at interpreting photos of candled eggs, so I can't say for sure. The real proof will be if the eggs hatch, or if you crack them open and see obvious development.

Well I'm a third of the way there nearly half way there now might as well just keep em incubating ay mate? Do U see the difference in the pics of the 2 incubated eggs tho compared to the eggs that look totaly clear from the cold draw?

It might be the fault of what screen I'm using to see the photos, but I don't actually see veins in any of them. For the incubated eggs, I think i'm seeing an overall darker appearance (maybe thicker shells or darker brown shells, maybe something inside the eggs), and I see light spots where the shell is probably thinner.

If they are developing, and your light is bright enough, and the shell is not too dark, I might expect them to look like some of the images near the top of this page:
https://incubatorwarehouse.com/pages/egg-candling
I've seen similar things when I've tried candling eggs, but I've also had times when I couldn't see anything because my light wasn't bright enough. And I've had times when the light was bright enough but I could only see inside some of the eggs, because the others had shells that were too darkly colored. I've never tried taking pictures of eggs when candling. So when I don't see anything in pictures of candled eggs, I know just enough to realize there are several explanations, and that I can't tell if they are developing or not.

Well I wud say it's a bit funny that it's only the 2 eggs I chose to incubate that have a "thicker shell' if it ain't veins or development wudnt U say? As all the others in the cold draw every single one of them is totally different.. completely clear can see all way thru every single one of them out the cold draw and see the dark air sack at end of egg, where as my incubated 2 there's clearly a dark network of something happening inside those 2.. I can't see thru the only 2 I'm incubating but I can see perfectly clearly thru every single one of the eggs in the cold draw... The incubated 2 are deffo different to every single one the others in cold draw iv just checked every single one of them.. all clear can see thru every one of em n not able to with the 2 that I'm incubating...

Incubated

Now From cold draw un incubated no dark network going thru it can see straight thru every egg from cold draw
