Can someone make a Video of Vent Sexing?

[MicroFarmMom]

Im trying to vent sex 2 birds but Im having trouble finding the vent o_0 and trying to figure out how to hold them still while I look for it. Etc. A video would be super helpful!!!

FOAM CHECK REQUIRES BIRDS TO BE MATURE AND IN BREEDING CONDITIONS... VENT CHECKING IS DIFFERENT AS YOU ARE ACTUALLY LOOKING AT THE VENT, AGAIN ITS EASIER WITH MATURE BIRDS.

Yup! I'm not a vent checker or bump squeezer, but it's next to imposable to sex any (Non color sex-able) coturnix, if they are not of breading age, and without adequate lighting to bring them into season.
