Wagtail
Horse servant
If I have the vet coming I stick a bit of chicken wire over a barrow and use it as a sieve
On a weekend I use a very fine fork (the sort used for woodpellets) to rake over the bed (like you'd rake up leaves) and find that pulls a fair bit to the front that then gets scooped up and disposed of
In general though I think the best way is to try and configure the stable to minimise traffic over the bed, things went from bad to worse when I moved the haynet location!
Chicken wire - great idea!
