one of my Blue French copper marans chicks is worrying me. She seems very quiet and withdrawn, and although she’s walking and eating and drinking she sometimes seems a little Unsteady on her feet when she does a poo which looks normal, seems to need to sit back for a bit or just wobbles a bit. I’ve given her some nutri drops. Any ideas or suggestions? It’s gone very cold suddenly here in Scotland today, it was 1C this morning.
