I was checking my girls out tonight as I was locking up their coop and noticed that 75% of my chickens have both lick and mites! We just moved them into their new larger coop that we finished building 2 weeks ago so they must have brought them from their old coop. My big concern is I currently have 18 two week old ducklings, 23 two week old chicks and 10 four day old chicks in the coop in brooders! I imagine the babies will be too young to treat? I did not check the babies because I had already had my hands on the adults and didn't want to transmit anything even though they are all in the same coop. I plan on stripping all the bedding out of the coop tomorrow and cleaning it completely. What should I use? I plan on bathing all the adult chickens as well. I have a bag of DE that I can use in the coop. Do I need to treat them with something else as well? What should I do for the babies?
