YES!!! I have sand in the run and in the coop, so, even if I haven’t scooped poop yet that day, by the time the girls meander from the run into the nestboxes, their feet are clean and dry.
In regard to using sand in the brooder, I use a flat panel heat plate -not a heat lamp. The heat plate does fine in the sand. It doesn’t get too hot. I have the heat plate that can be lower in the back (adjustable legs), and so during their first week or two, I keep the back lower than the front. That way, they can move to the front if they get too hot.
I think it’s certainly worth a try with your Silkies. I have lots of feathery feet in my coop and they stay pretty clean. My two light Brahmas don’t have bright white feet, but that’s because they love, love, love to dig through the garden and in the woods!
