I currently breed mice, rats, gerbils, and guinea pigs for feeders and to sell to local petshops. I also breed rabbits on a fairly limmited basis for pets. But I just had a request for a 5 day old rabbit and a 1lb rabbit, frozen, as feeders. I have never killed a rabbit and have really no idea of how to go about it. What do I do with the pinky rabbit? Put it in the freezer like I would a mouse or rat pink? Is that humane for rabbits? Or do I use CO2?

I've looked online and can't seem to find very much on rabbit feeders and nothing has said how to kill a pinky rabbit. Any help would be appreciated. Thanks.
