Picking up a newborn calf and transporting when necessary is not as easy as it was in my younger days. I'm sure others have ideas about how to handle this job. My solution: I had a three point hitch carry-all frame that I wasn't using; I built a box of plywood and attached it to the frame. The box is solid on the front and both sides. It is open on top and the back. On each side at the rear I put two parallel strips with a gap between them. This provides a track for a slide-up door that is raised just before loading the calf in the rear. Back the tractor right up to the new-born raise the door and scoot him in without lifting him over the top. Of course normal precautions with mama are still required. Make sure mama knows the calf is in the box and she will follow the tractor as you move the calf.
