Hi everyone! I just got all my new chicks for this year. 4 of them are black sex links from TSC. They all are look dirty and as if feathers are missing. But one in particular is looking very bad. I call her “ugly duckling”. Other than looks, she seems fine. She’s energetic, eating, drinking, playing, napping... all like a normal chick. Is this “moulting” and is normal or do I need to do something to help her/then all.
