Nest building 101

The hoglets have grown quite a lot over the last few days,so we have had to separate them into two groups. This is one of the smaller hogs and is getting to grips with building a secure nest. He's good at getting the materials,but once in his mouth, he's not sure what to do with it, so he runs around the cage looking for the bed.
Weight wise they are heading towards 400g. The speed they're putting it on we will be able to put them outside in the pre-release pens in a few weeks.
