Feeder breeders do however, 'flick' their heads to kill pinks as humane form of euthanasia.
I do agree with you 100% that freezing is painful. But in a case of pinks, it is more humane to freeze them straight out then put them through a gas chamber and have them survive. All rats older than 2 weeks old can be humanely euthanized in the typical fashion of CO2 or cervical dislocation.

Feeders cannot be decapitated of course, but the general method is there....
That's cool. Thanks!
