This technology has existed for quite a while now, I think well over 10 years. Talking to farmers, they are also well aware of it, but like tangential technology within dairy farming, the main reason they aren't using it is costs. Any added costs would have to be added to the price.

Where I live, the highest standard (in term of animal welfare) eggs costs around 40 cent per egg. The lowest standard cost around 10 cent, which is also generally the most sold type of egg. Getting this kind of technology widespread would either mean regulation + tariffs or getting it cheap enough that only cultivating eggs with female chicks in them becomes a cost saving technique.
