Most people seem to think the Chief Rabbis of Israel or the Temple Institute get to decide. The decision would probably be made before transport. These red heifers show up every so often and people use them to collect donations.
As an aside, the animal seems to be in a pretty ordinary pen with poorly maintained barbed wire fence where it could get a disqualifying cut or other injury. I’d be a little more careful with it.
Just watched the video, and payed particular attention to the wire enclosure. It’s not barbed wire thankfully. It looks to be plain wire, usually used for electrified fences. I don’t think it’s turned on. The hefer is pretty cute. :)
