ETR, that is a *brilliant* design. I may try making something larger-mesh like that for stalls, if I ever get bored. I do like to thoroughly-thoroughly clean the stalls every so often, and have always done it by tossing everything against a wall (the chunks of missed manure run down and accumulate around the edges of the pile where they can easily be scooped out) but every year the dust from that bothers me more and more.
If that design is your own, you should think about either patenting it if you're ambitious, or getting it published in a magazine if you're not so ambitious.
Seriously!
Pat, wondering whether "I want to try out someone's design for a goat poo sifter" would be enough to convince DH that we should get goats... alas, it probably wouldnt <g>
