I am always hearing about people dusting their birds and stuff. What do you dust with? I have DE and sevin dust poultry and lawn though. I will check my feed store for an actual poultry dust but wanted to know if I could use what I already have. What age can I dust and how often? I have 2 month old silkies now and don't know if I should dust them this early. Any info on dusting would be great!
