When I cleaned out my chicken house today I noticed lots of white dust almost like tiny crystals in their trays. All the chickens seem healthy but are moulting and not laying, but all so much better than three weeks ago. Does anyone know what it is (it's not mite powder) please & also if I should be worried. i'd be hugely grateful for any advice.

I'm not sure, as I'm no expert, but I think its a sort of dandruff called 'dander' something to do with the new feathers? I'm sure someone with more knowledge will post in a minute!!!

Thank you so much. That was exactly what I thought it looked like, but I thought I was just being silly!!!

Yes, it certainly sounds like part of the moult, bits of feather shaft I think. As you know yours are moulting, that'll be the answer, nothing to worry about.
