What is the light yellow/tan bug all over my chickens rump?? I noticed a few little black mites in the coop so I dusted the chickens and the coop with DE. When dusting the chickens I inspected them and noticed one of them had these other "bugs" on its vent area. I bought poultry dust because I was told DE wasnt entirely effective but I've been scared to use it. I've been noticing a few more mites so I finally broke the poultry dust out and now my other hen has a ton of those tan things all over heer vent...the others wasnt noticeable. Is it another type of mites? Fleas? Should I sprinkle the poultry dust in the coop and run?? I was thinking that didnt seem right to just leave a poison on the floor of their coop...to easy to ingest...but is that what I need to do to get rid of all the unwanted little pests??
