Hello! New to chickens here! This morning when I was checking on my three chicks, I noticed one is now making a coughing/sneezing sound. She seems okay otherwise but the noise is really concerning me. She’s a little less than a week old. She’s in pine bedding, and has been drinking and eating normally (just chick starter.) She has had a couple pasty butt run ins but seems to be okay in that regard right now. She is a Black australorp (the black and yellow one.) Is there anything I can do to help her?
