I am not sure if it is Lice or a disease, but i need to figure it out so i can safe my other 19 chickens from it. Okay... last night i found my little black hen Domino curled up outside and she didnt look good so i brought her inside and put her in my bathroom with a little heater to help warm her up. I looked her over and she seemed okay. I checked her legs to see if they had frostbite, but they looked okay. But then i realized she had bugs crawling on her. So my first thought is they are mites, so i looked them up on the computer and they didnt look or sound like what others described so someone on here told me it might be lice. Which i think it might've been. So sadly last night she died But then this morning I come out side and all the chickens are running around in our horse pastures, but to my astonishment I opened the big coop door to see my big ISA Brown rooster laying dead on the floor. I was stunned the most gentle rooster i have is dead. So i look around then realize that something is really wrong, so i take him out to bury him, then i go and get my mite dust but we barely have any left, ugh! So what do you all thing happened? And what should i do to keep it from spreading to the other chickens?
