The horned sheep sheep-feeder

 

Sheep with horns have a problem at a feeding trough. They can get their horns stuck under the metal bars across the feeding trough.

Much pulling and tugging ensues, as you might suspect

So "something  must be done ". 

I've got various length of drainpipe that first made an appearance last year  as part of an attempted Archimedean Screw 

It started like this

Gets cut in half

  has some blocks added to the end ( and some drainholes through the pipe )

And the horns don't get stuck! 

 

 I wonder if it will blow away in the winter .
