Yes. There's a system that's being developed for commercial layer hatcheries to reduce hatching and culling male chicks by using a laser to bore a tiny hole in the shell. A tiny needle is inserted into the egg to extract a small sample for DNA testing, and the hole is sealed off. It's still in the developmental stages, and costs a staggering amount of money to implement. Short answer... yes it is possible to tell the gender of a chicken before it hatches. Is this technology available for the general public? Short answer... no.
I would be interested to see if this ever gets to the stage of widespread commercial use.
If you want to sex your chick (like some peafowl people do) it costs about $40 per sample.
