HELP!! Female breeder rat cant' control its head movements

Yea it was kind of sad to watch. Really unexpected, she wasn't very old at all only her second litter and she was a really good mom so its pretty disappointing and I felt for her for sure.

Well, I was trying to be nice to see why he felt like he needed to cull the whole bin even though I don't see a reason to with an inner ear infection.

Yes, it is very sad. But these types of situations happen when breeding any type of animal. The reason we breed, however, is to be sure our feeder animals are well taken cared for, even if it calls for euthanizing a breeder to end suffering.

^ well put
