Symptoms? Age? Temperature? Feed?I am having such a hard time with my Silkies. I have lost 6 out of 7. I life in Oklahoma and I make sure they're always warm at night, always have food and water, I've put ACV in their water, given them boiled eggs, yogurt, make sure they are able to get away from the light and I just keep losing them. Any suggestions? Also, If anyways on here is in Oklahoma or knows where I can order older chickens, that would be great!
