I have the side of an old supermarket milk trolley, looks like a hurdle but with lots of small metal squares (3cm/3cm) I have tied it to a flat back of fence and then shove hay in between! its great, no wastage with the sheep. Goats on the other hand would probably naff it up, they have haylage nets now we have no young'ns to strangle themselves and are fine. THere was a golden guernsey kid strangled itself up the road in a proper, shop bought hay stand/rack once.
