spots in eggs

[CB3fish]

I grew up on a farm. we had 30 or more chickens composed of various breeds. Yes we had a rooster. Some times my mother would announce there was blood in an egg; she would not use that egg; it did not go to waste, she fed it to our dogs which she said gave them beautiful hair. I have chickens now and blood is rare but I have seen it. I do not believe it has anything to do with a rooster. I have not had a rooster for months and there was an occurrence of blood! I have a rooster now and no blood for 5 months. I have read that a fertile egg can be detected by a small drop of turbid looking fluid located in the white of the egg looking like it was attached to the yoke? I have a Moran rooster now and he is breeding those hens very very frequently!! BUT I am concerned that I see all kinds of specks in my eggs/ Not every egg but a lot of eggs have a dark speck!! What is that and what causes these specks. When I bought eggs I did not see any spots and I buy organic eggs. Now my chickens are in a large pen on the ground. Is it because they are on the ground? Is the reason I do not find the specks in commercial eggs is because the hens are in cages and are not on the ground?? What do you all think??

Commercial eggs are candled and those with meat spots/blood are sold for use in baking. These 'specks' are a result of a glitch in the egg development process and are generally sloughing from the reproductive tract. Do an on site search on 'fertile eggs' And pictures/threads should appear.

A blood spot in the egg is from a ruptured blood vessel somewhere in the oviduct, not from breeding.
The way to know an egg is fertile is to detect a blastoderm from a blastodisc. Almost imperceptible. I usually need to use a magnifying glass.

By the way, eggs with blood spots may not be pretty but they are just as edible as those without.
That process Sourland mentioned of candling and sorting commercial eggs is automated and at lightning speed.

We eat them just the same

Blood(broken blood vessel) and meat spots(piece of tissue) are pretty normal...
....some birds can have them more than others.
I think it's explained in this excellent video, which is worth watching regardless:

I find it hard to understand that commercial egg producers candle eggs when thousands are processed daily! Unless it is mechanized? Candling eggs is a time taking event.

Such a process would have to be, however, I do not remember spots being in our eggs years ago. Blood yes and but the blood spotted egg maybe okay to eat. I still do not use them. Thank you.

Maybe you are too young to remember. I certainly remember them but then, I'm old as the hills.
I used to program the ABB robots in the following video. The candling happens at about the 2:40 point.

This is perhaps even a better description of the process at a 3 million egg a day facility.

A single egg production facility with its own feed mill, 1 million pullets and 3 million layers automated egg processing.
