4 Year old jersey oxen

I broke this team of jersey for my kids to play with, when they out grew the kids I gave them to my cousin to use on his farm, only because they became pets and we were trying to avoid the slaughterhouse. He has not used them much for a year and has decided its time to move them along. They weigh a around 1000 pnds each. I had this team broke like robots, they followed every command to the letter. If somebody wants them for oxen I’ll bring them back home and work them into shape again. I was worried they would not be strong enough to pull hardwood logs but I am sure they will do any chore around a farm or pull firewood sized trees no problem. Price negotiable.
