I got a black star (1 week old) which is acting normal and eating/drinking normal.
However, she is missing fuzz on several spots and her feathers do not look smooth like other breed that I have.
Should I be concerned?
That is fairly normal to have bare spots around the shoulders. My RIR's looked like that, and within a week or two they came in normally.
Your response made me feel so much better. I thought it's got a mites problem that spreads or something.
Your welcome. If there were mites or lice, you would definitely see them on chicks. That is a good idea to check them.
