The bit of sexing embryos whilst still developing in the egg is correct - this year or last year it was reported that Germany was going to make it law and the male chicks will be destroyed well before they're fully grown, they'll force large scale breeders to use the technique and also outlaw the killing of male chicks in by throwing them alive in a mincer - and maybe the other ways of destruction, too, can't remember the details (nor, annoyingly, how the sexing-in-shell is done).

But as Marigold says, that still doesn't answer her question. Can't imagine it's done by AI, far too many chickens required. Are those cockerels super shooters? :)

Well, SOMEBODY must know, it's obviously big business involving huge numbers of parent birds.
I feel like when I was a kid, in an all-female family, at a girls' school, having rejected the gooseberry bush and the stork as impractical, trying to work out the mechanics of human reproduction in the days when nobody told young ladies the details about how exactly to go about it. With no chance of researching the internet in the 1950s, I remember light dawning after I read an explanatory limerick on the wall of the school toilets. Compared with the other theories it seemed equally improbable, but I resolved to give it a go when the opportunity arose.
But it didn't say anything about chickens.

This will hopefully shed some light.

Fascinating, thank you Dinosaw.
So that's how they do it in Kenya. Anybody found anything about how it's done in the E.U, or about how a large fertile egg farm is managed? They must be quite common, seeing as there are so many thousands of chicks required, not only to become egg laying hens or meat birds, but also to replace the parent stock - I don't suppose they go on anywhere near retirement age! We are all familiar with pictures and articles about intensive egg and chicken meat production, and surely there must also be regulations etc for the management of breeding farms?

I found a figure for 2012 of 6.8 billion laying hens that year (producing 65.5 million tonnes of eggs, though that was a different source and there seems to be a wide range of estimates.)
So at least 13.6 billion eggs were hatched, half being male.
If the breeding stock were producing 300 per year each (maybe?) then there were 78.7 million parent hens
With 10 hens to a cockerel thats 7.9 million males (assuming AI was fairly small scale in 2012 (I think it probably still is, particularly for layers who don't have the weight problems of meat birds)) and lets face it, the labor force work for chicken feed!
Now I'm losing the plot,but,
If a hen needs to be inseminated once a week? 52 weeks in a year (average around the globe)
that is 4.1 billion matings a year - thats 130 fandangos a second!
... something not right there - I think ...
Its quite a lot!

The same way I would imagine Marigold, just with more staff stimulating more cock birds and inseminating more hens. If you imagine a production line of cocks, hens, extractors and inseminators you can produce an awful lot of fertile eggs. One sperm harvest from a cock will in theory produce 140 chicks as it will produce enough sperm to fertilise 10 hens for 14 days. Therefore you roughly only need one cock for every 140 hens in reality as you would inseminate on a rotational basis. If you imagine that a facility with 14,000 hybrid layers would produce close to 4.2 million fertile eggs per year (14000 hens x 300 eggs) then you would only need 100 cocks for 4,200,000 new chicks per year, providing that is that i haven't missed out a zero somewhere at this late hour. So 1000 cocks for 42 million eggs, 10,000 for 420 million and so on. How long would it take one person to extract semen once they got good at it?, a couple of minutes?, boring job but even if you call it three minutes a go you could be extracting semen from 20 birds per hour, 140 per day if we call it seven hours allowing for breaks. One days work by one person could produce enough semen to see 1400 hens made fertile for a fortnight during which they could produce nearly 20,000 fertile eggs.

And then presumably the hens would have to be kept in batches numbered 1-14, and after they had arrived at Day 14, there would be another gynaecologist appointment, after which they'd pass along the conveyor belt to Pen 1 again. Actually it's probably less than 14, as there must be a drop-off in fertility towards the end of the 2 weeks, not a clear cutoff point.
And no chance to complain about sexual abuse,for either gender. I think my girls are luckier than they know, living in chaste single-sex retirement, where the occasional egg is greeted as a praiseworthy present.

I'm getting whacked just thinking about it! With turkeys? I bet that builds your biceps :)
