Hi, My 4 year old White Leghorn x New Hampshire is suddenly acting weird. She has her neck tucked in, her tail is dropping slightly, she's loosing some appetite, she's less active and her comb has gone a bit pale and floppy. I do live in Australia and so it's summer and beginning to get hot but my chooks have never done anything like this and they have water 24/7. Also, is her beak a bit overgrown? Any ideas? Her now: Her normally: Thanks.
